Redeployment of Azure Function does not happen - azure

I am experimenting with an Azure Function in PowerShell to answer a simple HTTP request.
I am editing directly in the Azure Portal.
I do not understand how deployment works. I assume it should directly redeploy after "save".
When I change my code and test it within Azure Portal I get debug results in the console/log and expected results in the HTTP-Output.
However: When I call the function from a browser, it returns different results. I think these are old results, so either the function is not redeployed or some cache / proxy is fooling my browser.
How can I see if redeployment took place after "save" in the AzurePortal?
How can I check debug / console output of a real invocation?

First, I run with the default Code from the Http Trigger Function (PowerShell Runtime) - i.e., created in the Azure Portal and edited the Function Code from the Portal itself > Saved > Clicked on Run again.
If we save the function, it will just save the changes in the code. We have to run again the Function for changes made in the Code Logic for new response.
You can see how many times your function in the Azure Function App is executed, in Monitor > Invocations with more information such as Response Code for every invocation (Function Run), Execution Time,
And I have updated the Function Code two times after 1st run of the default Code. Here in the Activity Logs, you can see number of times updated the run.ps1 function code updates registered:
Updated Answer:
I have run the Azure Function App PowerShell Http Trigger in the browser tab with its function URL for 4 times and the invocations are display after 4 minutes of time because my function app is hosted in Consumption plan:

Seems the function was "disabled" - after enabling it again all works as expected!

Blazor WASM Azure Static Web App, Functions not working

I created a simple Blazor WASM webapp using C# .NET5. It connects to some Functions which in turn get some data from a SQL Server database.
I followed the tutorial of BlazorTrain: https://www.youtube.com/watch?v=5QctDo9MWps
Locally using Azurite to emulate the Azure stuff it all works fine.
But after deployment using GitHub Action the webapp starts but then it needs to get some data using the Functions and that fails. Running the Function in Postman results in a 503: Function host is not running.
I'm not sure what I need to configure more. I can't find the logging from Functions. I use the injected ILog, but can find the log messages in Azure Portal.
In Azure portal I see my 3 GET functions, but no option to test or see the logging.
With the help of #Aravid I found my problem.
Because I locally needed to tell my client the URL of the API I added a configuration in Client\wwwroot\appsettings.Development.json.
Of course this file doesn't get deployed.
After changing my code in Program.cs to:
var apiAddress = builder.Configuration["ApiAddress"] ?? $"{builder.HostEnvironment.BaseAddress}/api/";
builder.Services.AddHttpClient("Api",(options) => {
options.BaseAddress = new Uri(apiAddress);
});
My client works again.
I also added my SqlServer connection string in the Application Settings of my Static Web App and the functions are working as well.
I hope somebody else will benefit from this. Took me several hours to figure it out ;)

Call azure function from another azure function in javascript

I am new in Azure technology. I have created two functions Master (masterFunction) and Child (childFunction) in Javascript.
I want to invoke Child function from Master function.
I have tried with childFunction.Run(req, log); but its not working.
Please suggest me to fix above issue.
Thanks
This does not work, the azure function actually executes code to meet the trigger conditions. For example, if your childfunction is triggered by a blob, then the way your masterfunction calls it is to satisfy the trigger condition of the childfunction, that is, add operations to the target blob in your masterfunction. If your childfunction is http, then you need to send a request to the childfunction url in the code of the masterfunction.

Error "BadRequest" when calling Azure Function in ADF

I am creating an extensive data factory work flow that will create and fill a data warehouse for multiple customers automatic, however i'm running into an error. I am going to post the questions first, since the remaining info is a bit long. Keep in mind i'm new to data factory and JSON coding.
Questions & comments
How do i correctly pass the parameter through to an Execute Pipeline activity?
How do i add said parameter to an Azure Function activity?
The issue may lie with correctly passing the parameter through, or it may lie in picking it up - i can't seem to determine which one. If you spot an error with the current setup, dont hesitate to let me know - all help is appreciated
The Error
{
"errorCode": "BadRequest",
"message": "Operation on target FetchEntries failed: Call to provided Azure function
'' failed with status-'BadRequest' and message -
'{\"Message\":\"Please pass 'customerId' on the query string or in the request body\"}'.",
"failureType": "UserError",
"target": "ExecuteFullLoad"
}
The Setup:
The whole setup starts with a function call to get new customers from an online economic platform. It the writes them to a SQL table, from which they are processed and loaded into the final table, after which a new pipeline is executed. This process works perfectly. From there the following pipeline is executed:
As you can see it all works well until the ForEach loop tries to execute another pipeline, that contains an azure function that calls a .NET scripted function that fills said warehouse (complex i know). This azure function needs a customerid to retrieve tokens and load the data into the warehouse. I'm trying to pass those tokens from the InternalCustomerID lookup through the ForEach into the pipeline and into the function. The ForEach works actually, but fails "Because an inner activity failed".
The Execute Pipeline task contains the following settings, where i'm trying to pass the parameter through which comes from the foreach loop. This part of the process also works, since it executes twice (as it should in this test phase):
I dont know if it doesn't successfully pass the parameter through or it fails at adding it to the body of the azure function.
The child pipeline (FullLoad) contains the following parameters. I'm not sure if i should set a default value to be overwritten or how that actually works. The guides i've look at on the internet havent had a default value.
Finally there is the settings for the Azure function. I'm not sure what i need to write in order to correctly capture the parameter and/or what to fill in - if it's the header or the body regarding the error message. I know a post cannot be executed without a body.
If i run this specific funtion by hand (using the Function App part of portal.azure.com) it works fine, by using the following settings:
I viewed all of your detailed question and I think the key of the issue is the format of Azure Function Request Body.
I'm afraid this is incorrect. Please see my below steps based on your description:
Work Flow:
Inside ForEach Activity, only one Azure Function Activity:
The preview data of LookUp Activity:
Then the configuration of ForEach Activity: #activity('Lookup1').output.value
The configuration of Azure Function Activity: #json(concat('{"name":"',item().name,'"}'))
From the azure function, I only output the input data. Sample Output as below:
Tips: I saw your step is executing azure function in another pipeline and using Execute Pipeline Activity, (I don't know why you have to follow such steps), but I think it doesn't matter because you only need to focus on the Body format, if your acceptable format is JSON, you could use #json(....),if the acceptable format is String, you could use #cancat(....). Besides, you could check the sample from the ADF UI portal which uses pipeline().parameters

Azure function published but not running, "no data available"

I can publish a Azure function from Visual Studio without an error.
This funtion is set to run every 4 seconds ("*/4 * * * * *") but it is not running at all. Even if I try to run it manually it do not run and show the following error:
Status: 404 Not FoundThe resource you are looking for has been
removed, had its name changed, or is temporarily unavailable.
Under monitoring it do not shows data, under success or error count it says no data available :(
Nothing is working please help
This is a pretty old thread but in case anyone is facing the same issue after migrating their Function App to .NET Core 3.1, check that you have also updated the Function Runtime Version to 3. Update the Function App SDK and in Azure portal check that the function runtime settings is 3. Without updating this setting the same 404 error appears whenever you try to call your function app.
For changing the Function Runtime Version open the Function App in Azure Portal then go to Configuration -> Function runtime settings. From the Runtime version dropdown choose ~3.
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.
According to your 404 error message, it means your function source couldn’t be found. Such as wrong resource path , function name has been changed, wrong function name or the function has been deleted.You could check whether your class name and FunctionName attribute name are consistant. If you have changed code, remeber to rebuild the project.
And please make sure you could run the Azure function successfully in Visual studio before published to Azure. In debug mode, check whether output logs are correct.
Under monitoring it do not shows data, under success or error count it says no data available
This info usually means function has never been triggered before. If you create a new function in Azure and click Monitor directly, you could also see this info. To solve this problem, unless you could trigger this Azure function successfully.
In my case I was deploying the azure function using the Azure Resource Manager (ARM) template. I created it manually and was missing some of the properties for the storage account:
For anyone deploying an Azure Function using an ARM template, I would highly recommend taking a template from the GitHub quickstart ARM templates: https://github.com/Azure/azure-quickstart-templates
It provides the minimum template to get your function (and other resource) up and running.
The issue with your function was that GetFTPData.cs is not a valid function name. VS build doesn't validate the function name and the portal isn't displaying these errors.
This issue is tracking the portal error display https://github.com/Azure/azure-functions-ux/issues/2316
and this is for VS build to validate functionName attribute https://github.com/Azure/azure-functions-vs-build-sdk/issues/174

Cloud Functions for Firebase error: "400, Change of function trigger type or event provider is not allowed"

When I run firebase deploy I get this error message:
functions: HTTP Error: 400, Change of function trigger type or event provider is not allowed
TL;DR
firebase functions:delete yourFunction // this can be done via the Firebase Console as well
firebase deploy
Explanation
Basically, Cloud Functions expects the same trigger for every function all the time, i.e. once it is created it has to stick to its original trigger because every function name is connected to a specific trigger. The trigger can therefore only be changed by deleting the function first and then creating it again with a different trigger.
This can now be done easily by using the functions:delete command:
firebase functions:delete yourFunction
The documentation features more advanced use cases as well.
Old solution
Solution of this is basically commenting or cutting out your function and then saving the Functions file and deploying. The function will get deleted in Firebase, but after that you can insert/uncomment your function and it will deploy just fine again. This error occurs when you take a function and change the type of trigger that it uses, i.e. HTTP, database or authentication.
Firstly cut it out
/* exports.yourFunction = someTrigger... */
And then, after deploying ("firebase deploy") replace your trigger
exports.yourFunction = anotherTrigger...
For those who stumble upon this in the future, the Cloud Functions console now offers a delete button.
You can also go to the Cloud Functions panel in the Google Cloud Platform console and delete your function from there. After that you can upload the function normally from firebase CLI. Not sure why they don't have a delete function option in the firebase console.
