[ISSUE] Error: cannot read workspace conf: unexpected error handling request: invalid character 'S' looking for beginning of value.

[gercograndia]

Description
When using the terraform databricks provider (version 1.39.0) we have quite regularly but not always this error popping up when planning or applying code. We have upgraded our databricks provider recently so I guess it is introduced in one of these later versions.

Seems related to issue #883 .

Reproduction
Just using the databricks_workspace_conf resource

Expected behavior
No error

Is it a regression?
It is a new issue to us, so my take is that this is indeed a regression.

Other Information

• OS: macOS and Linux
• Version: different but mostly recent versions

Debug Logs
Turning on the debug logs is a bit difficult when you don't know when the issue appears. But this is the already pretty verbose error message that you get:
