I'm facing the below error in REST Receiver channel (via OAUTH 2.0 Grant type).
Catching exception calling messaging system: com.sap.aii.adapter.rest.ejb.common.exception.HttpCallException: HTTP OAUTH 2.0 CLIENT CREDENTIALS GRANT call to https://url.com:443/api/authentication/access_token not successful.
Error while obtaining access token - response code: 400 response:
"error_description":"Client authentication failed",
Thanks and Regards,
