Failed to add an app setting named AzureWebJobsFeatureFlags constrained by Azure Static Web App while required to re-enable proxy

Hi All,

I have an azure static app with self-managed api in .netcore3.1 in which a proxy has been defined.

After migrating to net6 and v4 azure function, the proxy stopped working.

By checking Mircosoft documentation, a flag named AzureWebJobsFeatureFlags can enable proxy functionalities. However, azure static web app doesn't allow to add an app setting has name prefix using AzureWeb.

https://learn.microsoft.com/en-us/azure/azure-functions/legacy-proxies#re-enable-proxies-in-functions-v4x

Could anyone provide a solution or a workaround?

Much appreciates for any hits.

Thanks,
