Describe the bug

I am unable to set a container image to function apps using Azure CLI. The function app is under "Container Apps Environment". I am able to do the same using portal, just that it won't work in CLI. The error is "Internal Server Error", doesn't provide much information as well.

Related command

az functionapp config container set --docker-custom-image-name .azurecr.io/:4338e0ec91f0bb3216e4 --docker-registry-server-password --docker-registry-server-url https://.azurecr.io --docker-registry-server-user --name --resource-group

Errors

Operation returned an invalid status 'Internal Server Error'
Content: {"Message":"An error has occurred."}
