I’m doing a deployment for an Azure Function using Github Action. My function has this env var:

But when I run the Action the deployment fails with this error:

If i check the log from Application Insight I find this problem that make me think that there are some problems accessing the keyvault (although the function has access):

In fact if I change the value of AzureWebJobStorage using plain connection string (eg “DefaultEndpointsProtocol=https;AccountName= …”) the deployment works just fine.
The thing that I found most tricky is that if, after the successful deployment, I revert the env var AzureWebJobStorage to point again to the KeyVault all the next deployments work!!!
Someone can explain to me what is happening here? Thanks a lot.
