Azure Function Not Triggering After Deploying New Version with VNet Integration
I'm stuck trying to I've encountered a strange issue with Quick question that's been bugging me - I'm learning this framework and I'm not sure how to approach After trying multiple solutions online, I still can't figure this out. After deploying a new version of my Azure Function that uses VNet integration, the function no longer triggers as expected. The function was previously configured to respond to HTTP requests, but now it returns a 403 Forbidden behavior when invoked. I've checked the network settings and confirmed that the function app is correctly integrated with the VNet and has access to the necessary subnets. Here's the relevant part of my host.json configuration: ```json { "version": "2.0", "extensions": { "http": { "routePrefix": "api" } } } ``` Before the deployment, I was using Azure Functions v3.0, but I've updated to v4.0 to incorporate some new features. However, I made sure to follow the [migration guide](https://learn.microsoft.com/en-us/azure/azure-functions/functions-versions) properly. I also verified the Azure Function settings, and the Function App is still configured to use the correct Storage Account and App Insights. To troubleshoot, I checked the logs in Application Insights and found the following behavior message: `"The caller does not have permission to perform action 'Microsoft.Web/sites/functions/execute' on resource..."`. I've ensured that the Function App's identity has the necessary permissions assigned in the Azure portal. I also tried disabling VNet integration temporarily to see if it triggers without it, but that still resulted in the same 403 behavior. Since this is a production deployment, I'm hesitant to roll back the version without fully understanding what went wrong. Is there something I might be missing regarding the function's authentication settings or VNet permissions? I would appreciate any insights or recommendations for debugging this scenario. My development environment is Windows. Any help would be greatly appreciated! What would be the recommended way to handle this? I'm working with C# in a Docker container on macOS. Thanks, I really appreciate it! My team is using C# for this application. The stack includes C# and several other technologies. Am I missing something obvious?
