Hi,
While invoking API calls, you can also send other parameters like, Scope & Grant Type.
Please check with your API system, whether the parameters are correct (or) not.
This could helpful to resolve the issue.
By looking the error, the error seems to be “Unable to identify the application for the request - User - Default and Application:null”. So this means that, the request is in API server & not able to identify the correct application. Please engage with API team & found out RCA.
Thanks,
Srinivas
