Hi Abhinav, After checking the provided logs, it is observed that you have encountered the "OAUTH_TOKEN_HEADER_INVALID " error when trying to make a request to the searchStream.
It appears that the credentials sent in your HTTP request are not valid and this is why you have encountered this error. The prevention tip recommended is to make sure you've passed the correct access token associated with your account. It's sometimes confused with refresh tokens and authorization codes. If you would like to get a credential that can access all client accounts under a manager account, make sure you get the refresh token for the manager account. For more details, see our guide on access token and refresh token and OAuth2.
