ARM Template to add named Event Grid System Topic fails with 'internal server error'.

Question

ARM Template to add named Event Grid System Topic fails with 'internal server error'.

Kirk B 1

Using https://learn.microsoft.com/en-us/azure/event-grid/create-view-manage-system-topics-arm as a reference, I am trying to add event subscriptions to a named system topic using an ARM template. It fails for me with the messages below, essentially "internal server error." I'm hoping the GUIDs below will point someone w/in MS to the problem.

But if not, where can I take these GUIDs to get some resolution?

Thank you

Hi @Kirk B

Welcome to Microsoft Q&A! Thanks for posting the question.

I have looked into the backend logs for the tracking ID provided in your exception I can see that the event grid was not able to add your function as the destination endpoint since your Azure Function was not in the Active state.

Can you provide more details on the ARM template and if you are creating the azure function in the same template?
Please confirm if the resource dependencies are set correctly using dependsOn.

@MayankBargali-MSFT ,

Thank you for looking at this.

To answer your question regarding "dependsOn", all I have defined is that the eventSubscription depends on the systemTopic. Would I also include the function app and its function as dependencies? The function is referenced in properties.destination.properties.resourceId.

So you cannot create a subscription to a function unless the function is in an active state, is that correct? To be active, does that mean that there has to be code deployed as a function app, with function endpoints defined? There is no way to do this in an ARM template, is that correct?

Thank you for your time.

Hi @Kirk B

Thanks for sharing more details.

Would I also include the function app and its function as dependencies.
[Mayank]No, you don't have to define a dependency on function for event subscription. The only need to define a dependency on the system topic. But the topic should have dependency on function app resource.

So you cannot create a subscription to a function unless the function is in an active state, is that correct?
[Mayank]Yes, you cannot create a subscription until that is in the active state.

[Mayank] Function should be deployed before configuring the endpoint in event grid subscription. Yes you can but you need to deploy the function using WEBSITE_RUN_FROM_PACKAGE

You can refer to this ARM template for reference and modify as per your need.

Is this only for ARM? I can create a function via arm with no code deployed to it, and use it as an endpoint for an event grid system topic subscription, as long as I make the subscription using the portal. But making the subscription via ARM alongside the function, creates this error (even with the necessary dependsOn, etc).
