Salesforce activties - error unsupported token

Hi All,

Salesforce application scope is giving unsupported token error. authentication is successful whil running lightining api activity i’m getting this issue.
I have added retry scope activity, with retry it works sometimes but mostly it’s not working when volume is high.

Any idea what could be the cause and how to fix this issue.

Thanks!
