Description

This issue has been raised by the Azure Identity SDK team while adopting msal-node's Managed Identity implementation.

On error, something like this is shown as the error message.

ServerError: bad request: undefined - [undefined]: undefined - Correlation ID: undefined - Trace ID: undefined

Question: Does the IMDS endpoint return the data needed to populate the error message
here?

Answer: a managed_identity_request_failed error should be thrown, showing the correlation id and any other details returned from the managed identity source.
