I'm trying to set up an Azure Function that I want to trigger when a message is put on a Service Bus queue. However, I can´t get it to work. The first "log.Info" does not trigger.
I deployed an Http trigger together with my Service Bus trigger and that works.
Some screenshots is shown below. I´ve already tried to remove the json string with key "generatedBy", as I saw as a suggestion on Google.
There are two files in my Visual Studio project which I have not edited: host.json and local.settings.json, I can´t find information about how to set them up or if it´s necessary at all.
Can anyone help me?
The Connection property of ServiceBusTrigger attribute should refer to a setting name, e.g. ServiceBusConnectionString.
Then, you should put the setting with same name to local.settings.json for local development and to Application settings for Azure.
I needed to append this bit to my ServiceBusConnectionString when running locally:
;TransportType=AmqpWebSockets

Is it possible to lookup the application name for an Azure app as it runs, i.e., get the information about that is displayed in the Azure portal? In the example below, I'd want something to tell me from within the application that I am running sitemap-prod-eastus.
I've been looking at the Azure Context object but not seeing what I need. There is an invocation ID, a name for the function, a directory - not the info in this window.
Maybe this can be done through Azure Application Insights?
I am working in Node JS.
I've not seen anything that would expose this to a function app. That said, there is one sort of workaround that you could do which would work - go to the Configuration blade for the function app, Application settings tab, and add a configuration key like function_name and set its value to the name of your app. Your app could then just read it out of configuration.
It's an extra step, but if you're doing it with something like ARM or Terraform, it's just another configuration entry with a variable you already declared to set up the app in the first place.
Answering my own question: Azure provides WEBSITE_SITE_NAME in the runtime environment that matches the name of the function app.
Lately I've had trouble with deploying a Function App via Azure CLI. Last week on Tuesday, I was still able to deploy a Function App via Azure CLI.
This week, like any other day before that, I used fairly common Azure Function Tools command func azure functionapp publish. The version of Azure Function Tools I am using is 3.0.3233.
Now I am getting this error every time:
Retry: 1 of 3
Error creating a Blob container reference. Please make sure your connection string in "AzureWebJobsStorage" is valid
Retry: 2 of 3
Error creating a Blob container reference. Please make sure your connection string in "AzureWebJobsStorage" is valid
Retry: 3 of 3
Error creating a Blob container reference. Please make sure your connection string in "AzureWebJobsStorage" is valid
I checked that AzureWebJobsStorage setting has a correct value, I even connected to storage account connection string via Azure Storage Explorer app.
Just in case, I created a new Function App in another region and I still get the same error.
Has anyone else encountered this error? I suspect this is an error in the tool itself, maybe a faulty build?
I suspect that AzureWebJobsStorage is not present/invalid in App Settings section of the function app in the Azure portal.
Make sure that it is added there and you are not deleting those settings through CLI/templates and recreating them without AzureWebJobsStorage.
I answer to my own question. It seems that this was a transient error. Without changing any code, today I was able to redeploy my function app. Cheers.
If you don't have "Allow storage account key access" enabled , you get this error.
There could be other scenarios as well. But the error does not say anything .
I have several Azure Functions Apps (c#, javascript and python) and after some time they were all randomly set to Read Only mode. The strange thing is that only one of these 3 function apps were updated before this happened. I know that this is not necessarily a problem, but I want to be able to make edits from the portal.
I can't open App Service Editor
I can't set the app to Read/Write from Function App Settings -> Function app edit mode
I also tried using "func azure functionapp publish myAzFuncAppName --nozip", but with the same result
Of course. Please notice that if the function is 'deployed' to Azure, what will be deployed is the compiled file.
For example, if you deploy C# function app, what will be deployed is the dll file. So this is why it is readonly.
Changes to the code should be done before compiling them into corresponding 'cannot be edited' files, which requires special attention.
But for the modification of the declarative part and the configuration part of the function, this is possible, the specific steps are as follows:
Declarative part:
Then click Debug Console > cmd:
Go to site\wwwroot[yourfunctionname], and there will be a function.json.
Click the 'pen' to edit and don't forget to save.
Configuration part:
You can change the settings from Azure Portal or by editing the application settings. FUNCTION_APP_EDIT_MODE allows values readwrite and readonly, a
Just deleted the Azure Function App, created a new one, transferred the code in the new one and deployed -> still read only, but now I was able to open "App Service Editor" and remove "generated by..." from function.json and then set "Read/Write" from Function App Settings -> Function app edit mode.
Still... I can't see/edit the code of the function, only of function.json and if I redeploy using Azure extensions of Visual Code or powershell with --nozip attribute, the "generated bla bla" appears again :(
When the application runs from package, the files are loaded from that package. Hence those files are not editable.
You need to set WEBSITE_RUN_FROM_PACKAGE : 0 in app settings and redeploy the application again to make the function app editable.

UPDATED:
You can deploy functionapp through command line from visual studio code. Try below command.
func azure functionapp publish --nozip
The nozip flag would set Run-From-Package mode off .
you can access other information regarding that command with func azure functionapp publish --help
So I am trying to get Let's Encrypt working on Windows Azure through the web extension but I am getting a error that I cannot solve or find any information about.
I am following this tutorial on how to set ut Let's Encrypt on Azure:
https://github.com/sjkp/letsencrypt-siteextension/wiki/How-to-install#create-a-service-principal
When I use the extension wizard, fill in all the fields and press next this is the error I get:
My resourcegroup:
My serviceplan inside my resourcegroup (+ storage and app service):
My ClientID (application id):
My secret is also set, saved the value and pasted it into the wizard:
My connection strings are set (in the format mentioned in the tutorial/setup):
There is a webjob running, I did not create this, I think it was created by the wizard in some way(?):
And at last:
It seems to me that I have done everything the tutorial has asked me to do, I don't know why I get the error, I also don't understand the reference to "00000000-0000-0000-0000-000000000000". Does anyone know what I did wrong and how to solve this error?
Thanks in advance.
The checkbox "Update Application Settings" must be checked if you want to modify the settings from the Let's Encrypt extension's pages.
If you hate the idea of an azure webjob swallowing valuable system resources of your azure app service then there is now an alternative solution which uses Azure Automation;

I created an Azure Function App in Visual Studio 2015. The App has a trigger for service bus queues. The app works perfectly when I run it locally. It is able to read the data from the Service Bus queue (configured via a variable named AzureSBConnection) and log it in my database.
But it gives me the following error when deployed in Azure:
Function ($ServiceBusQueueTriggerFunction) Error: Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.ServiceBusQueueTriggerFunction'. Microsoft.Azure.WebJobs.ServiceBus: Microsoft Azure WebJobs SDK ServiceBus connection string 'AzureWebJobsAzureSBConnection' is missing or empty.
Note that my connection is called AzureSBConnection and not AzureWebJobsAzureSBConnection. Also, the connection works locally. And finally, the deployed file looks exactly like the local file.
The Visual Studio structure looks like the following:
The function.json file has a bunch of settings as shown below:
Then in the Appsettings.json file, I have the following:
For deploying, I FTPed the files to the D:\home\site\wwwroot location for my Function App in Azure. The final structure in Kudu looks like:
And if I go inside my function folder:
Here is the deployed function.json:
And here is the deployed appsettings:
The deployed json files are exactly the same as the local files. But the deployed version is erroring out because of the missing AzureWebJobsAzureSBConnection. What am I doing wrong?
Only environment variables are supported for app settings and connection strings.
You need to make sure that the environment variable AzureWebJobsAzureSBConnection is set on your Function's app settings in the portal:
and then once there, you need to add the AzureWebJobsAzureSBConnection variable with the proper connection string:
and then you can access this via code by:
Environment.GetEnvironmentVariable(name, EnvironmentVariableTarget.Process);
This will obtain the value from either the appsettings.json or the environment variable depending on where the function is being executed from, (local debugging or deployed on Azure)
It is able to read the data from the Service Bus queue (configured via a variable named AzureSBConnection) But it gives me the following error when deployed in Azure:
After you deployed your application to Azure Function, your application will read the connection string from environment setting. Currently, connection settings in appsettings.json will not update environment setting automatically. We could click [Configure app settings] button as #flyte mentioned to check whether the connection string is configured successfully. If not, you could add it manually in app setting box.
Note that my connection is called AzureSBConnection and not AzureWebJobsAzureSBConnection
Please go to [Integrate] page to check whether the [Service Bus connection] is configured successfully. If not, you could reset it by clicking the [new] link.
