Why do I get 'Invalid dev-id was provided'?

The authenticateSDKUser endpoint returns Invalid dev-id was provided for any validation failure on that call, not only a bad dev-id.

Usual causes:

• An empty token header (token not generated, or placed in the body instead of as a header).

• A missing resource_user_identifier query param.

Capture the x-terra-trace-id from a failing call to map the exact request and identify the dropped field.
