    Hi Team,

    I am using IBM ISAM 9.7 Version and while calling API for token getting below error: 

    Access to fetch at 'https://example.com/mga/sps/oauth/oauth20/token' from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status.

    I have done changes in reverse proxy configuration file as

    [rsp_headers]

    Access-Control-Allow-Origin = *

    But above error is coming, please help with solution.
