🐛 What happened?

I tried to create a fabric connection using OAuth2 for Azure Databricks in Terraform (in the UI it works), but I got the following error:

I tried using an “unsupported” credential type to see what credential types are supported and I got the following list:

I decided to create the connection with another type and skip the test connection so the connection is created directly. Then, I would change it to OAuth2 in the UI, so I tried using the listed credential types above other than OAuth2 since it didn’t work, and I got the same error (the skip test connection value is not supported) for all 3 other credential types:
Basic:

Key:

ServicePrincipal:

During terraform plan, setting skip_test_connection = true in the credential_details block of the fabric_connection resource always fails with the error "Unsupported skip test connection", regardless of which credential type is used.
