I have an Azure WebJob and when it picks up a message from the queue I get the error
"Function had errors. See Azure WebJobs SDK dashboard for details".
The dashboard shows no errors, it just insists my connection strings are not set which they are or else it wouldn't pick up the message.
When debugging locally how can I find out what the actual error is?
You can debug locally by explicitly setting the Dashboard connection string to null in the JobHostConfiguration object. That will make the host show all errors in the console rather than dashboard.
What connection strings do you set (their names)?

I have an Azure function, which fails while running Startup.cs (while initializing the runtime) because it can't load a key from a Key vault. I would like to automate the deployment of this function in the future and therefore I would like to set up an alert to trigger if the function can't initialize correctly for any reason. (I can fix this speficic error, I just use it as an example).
At the moment I see the error in the Notifications section of the function page in the Azure portal:
I also see the exceptions in Diagnose and solve problems -> Availability and Performance:
But I can't seem to find a way to set up an alert to respond to this situation. I assumed that Resource health alert would cover this, but it doesn't. Maybe because to portal reports the function as Status: Running. I also can't find this error in Application Insights.
Is there any way to set up this alert?
To create the Alerts for Function App Runtime failures, start with the Alert Action Groups.
Open your function app in the Azure Portal and create the action group that points to your function and email configuration:
In the same function app menu > Logs > Get the Function Request Failure results such as below:
Then, click on “New Alert Rule” > Insert the values for Alert logic such as Frequency of Evaluation, Operator, Threshold Value, Measure of data summary, etc.,
Next, Select the Action Group which is created at the starting - that contains the Selected Function Data and the Email Notification configuration details:
After configuring the alert group, you’ll get the mail that the alerts are mailed accordingly:
I have given the wrong input to get the alert for the Function Runtime failure, which is driven to the Alerts:
Result:
For more details regarding Azure Alerts, refer to this MS Doc.
Updated Answer:
- This query gives the function errors messages in the logs and from this panel we can create the alert rule for the errors and warnings.
I've deployed and published several Function Apps without issues over the last 12 months. However, as of this week, when publishing a Function App using the following PowerShell script:
func azure functionapp publish <functionAppName> --java
I will receive the following error after a few minutes: "Timed out waiting for SCM to update the Environment Settings"
Similarly, I'm also unable to deploy any Function Apps, using:
mvn azure-functions:deploy
In the Function App activity log, the following error is logged for both cases:
Operation name: Sync Web Apps Function Triggers.
Status: Failed.
Error code: BadRequest (HTTP Status Code: 400)
Message: Encountered an error (InternalServerError) from host runtime.
So far I've created the Application setting WEBSITE_WEBDEPLOY_USE_SCM (value: true) based on feedback in another topic, which unfortunately hasn't helped. Other than that I've not been able to find much other information on this issue.
Does anyone have any thoughts?
Resolved this issue myself. The Application Setting WEBSITE_CONTENTAZUREFILECONNECTIONSTRING contained an outdated storage account key.
I am getting this error while trying to invoke azure function through the data factory. Snap of the error is attached.
I then again tried with the same parameters, and the next instance of execution just worked fine.
I just wanted to know if this problem is from azure server side or due to from my code.
Any help would be appreciated.
Call to provided Azure function 'OnCopySuccess' failed with
status-'InternalServerError' and message - 'Invoking Azure function
failed with HttpStatusCode - InternalServerError.
Has nothing to do with Azure DataFactory, it fails because of the Azure Functions, HAs from the error you will not be able to detect any issues so, you may examine the output of your azure function app using logs in kudu, in addition to the monitor of the azure function.
In addition, kudu log files are more timely than the Azure function's monitor.
Simply navigate to this website's address.
Click on the URL https://yourfunctionappname.scm.azurewebsites.net/DebugConsole
Go To: LogFiles\Application\Functions\Function\yourtriggername
The log files can then be found. The log file in Kudu is real-time, whereas the monitor takes a while to show (typically 5 minutes).
HTTP Function is supposed to actually return an HTTP result, See the Original Post - So you might check your Azure Function Code.
For some reason, I'm unable to make the connection from Stream Analytics to my Azure Function as an output. I have this exact pipeline set up and working in my own Azure subscription, but can't get this output connection to work in my dev environment.
Unable to load subscriptions PIC
First, the drop-down does not load the available function apps and functions in the subscription, as seen above. There are multiple that are in the subscription and are running, so this should populate. Instead, I see the error "Failed to load function apps" and "Failed to load functions."
Second, when I try to fill in the fields manually (after selecting "Provide azure function settings manually") I am also unable to connect. To do this, I'm giving the output a unique name, then copy/pasting the function app name and function name to the blanks. For the key, I've tried many variations to no avail. My function currently has Authorization set to anonymous, and I've tried leaving the key field blank. I've also tried using the "Function" key on my function, as well as the _master and default access keys. Each give me an error message when testing output connection. How do I get this connected?
Manual function setup PIC
Here is the error that I get
Error PIC
UPDATE - I'm still working on this, but at least part of it was due to having a hyphen "-" in the function name. Apparently Azure doesn't like that. Once I fixed the function name I'm able to trigger the function manually from within the Azure portal and externally through Postman, but still the connection test is failing from Stream Analytics.
UPDATE 2 - My temporary work around has been to have Stream Analytics post its output to an Event Hub, and trigger a function off of the Event Hub's traffic.
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.
