@Chedberg84 az webapp should not be used for functionapp - the az functionapp * commands should be used for functionapp & slots creation for functionapp is not currently supported.

👍 I am also experiencing this issue.

I am using an Azure Function runtime version ~2. Following the Terraform example here: https://vgaltes.com/post/deploying-azure-functions-using-slots/

I was able to confirm I see the same issue as stated by @exc3eed above when running the az webapp deployment slot create command. Adding the storage account connection string doesn’t seem to change the exception thrown:

Failure sending request: StatusCode=400 – Original Error: Code=“BadRequest” Message="Function App app settings are not expected to be empty. Please try again with WEBSITE_CONTENTAZUREFILECONNECTIONSTRING as a storage account connection string.
