Could you check if the Service Account under Connection tab is valid.

Yes It is validated successfully. The same Service account i was using for salesforce login and for connected app also.

What was the authentication type for the target API. Was that OAUTH2.0?

This issue has been fixed.

It is due to the Service Account does not have the ION API and Mingle Enterprise related roles assigned to it.

After assigning those roles to the Service account, I have imported it in the ION API connection point and tested the ION API CALL in the document tab of API Connection point.

Please find the below references.
