Please Suggest what can we do about it. Also confirm if we are doing anything wrong.

@rajpurohit303 There's something wrong with how you are providing your OAuth credentials. Could you directly mail [email protected], cc me ([email protected]) with details on how you are setting your OAuth credentials?

Also related: #23 for why the error message isn't too friendly in this case.

Looked at this. Essentially, the refresh token has been revoked. Obtain a new refresh token by running the GenerateCredentials example, and you are all good to go.
