Rest API Update Datasource returns an error when using UseCallerAADIdentity

Hey oyermokhin,

Did you ever figure this one out?

Trying to do something similar for a cloud SQL DB, but keep getting either 500s (when I omit `credentials` altogether), or 400s (when I set `credentials` to null or an empty object).

The docs are pretty thin on the ground, so it's not entirely clear which sources this can be used on. It says "For Extension data sources, don't set useCallerAADIdentity to true". Then it says "To set OAuth 2.0 credentials for other data sources, send the OAuth 2.0 token in the payload as shown in the OAuth 2.0 credentials example."    

So I can't use it for Extension data sources. And for other sources I need to specify the bearer token myself. I wonder - when can I actually use useCallerAADIdentity  then? 😅

If you know any more on this and are happy to share, that would be great.

Thanks,

Ed
