You likely didn't give proper credentials to the API. – JacopoStanchi
According to my knowledge I'm giving all required credentials, if possible please mention credentials information.means what I have to use.@JacopoStanchi – prahan
Have you checked the workaround here? – MαπμQμαπkγVπ.0

This is another disappointing design in the Gmail API. I resolved this issue with the following steps:

  1. Remove GmailScopes.GMAIL_METADATA from scopes setup.
  2. Remove the credential file from your local FileSystem. This file is generated by Google's Authorization Flow which store your credential locally.
  3. Re authorize your app by signing in again https://accounts.google.com/o/oauth2/auth?access_type=offline....

Hope this helps you guys out.
