I am getting "Exception occurred in Test Connection. Error: Exception occurred while generating access token: Unable to generate access token. Response returned: {"error":"invalid_client"}“}” while connecting to SaaS application using OAUTH grant type password. I am passing username, password, client_id and client_secret in the request header.
I am able to connect using POSTMAN to the application but for some reason ISC is throwing invalid client error. Using the developer tools, I figured out that access token generated by ISC is not a valid token but not sure why its invalid. Any pointers will help.
