Managed function in Static Web Apps cannot find module azure.mgmt

Sofia Louisy 40 Reputation points

I am hosting a Static Web App, where I deploy manually with swa cli. I have an api that needs to connect to other resources in the same resource group. For that, I am using the python sdk. It works as expected locally, but when deployed, the function cannot locate the sdk modules.

I cannot find anything in the documentation about these modules not being supported in managed functions. I have filled up my requirements.txt with the modules I need. Am I missing a step?

Exception while executing function: Functions.list_subscriptions Result: Failure
Exception: ModuleNotFoundError: No module named 'azure.mgmt'. Please check the requirements.txt file for the missing module. For more info, please refer the troubleshooting guide:

    I spent a considerable amount of time trying to repro your issue and came up short. I wasn't able to get the tooling to work on my environment with a backend Azure Function. I did try to deploy a simple angular app with a C# function. Using CI/CD I can see the deployment occurring and the api/message endpoint returning 200. When using SWA CLI deploy command, my api did not deploy and unfortunately, I don't see any logs that would help me diagnose.

    I would advise using yaml CI/CD pipeline to deploy your SWA with API. My gut tells me that the requirements.txt is failure, but there aren't any logs to review to confirm. So switching to a CI/CD pipeline will at least afford the ability to diagnose the deployment.
