The 'invalid_grant' error is usually noticed when the access token or
refresh token is invalid or incorrect. Could you generate a new refresh
token with the help of this guide
retry your request?
To verify that your credentials are correct, you could also try the CURL
request provided below and see if you are able to generate the access
tokens. If the credentials are correct, you should get an access token for
the below request.
curl https://www.googleapis.com/oauth2/v4/token \
-d refresh_token=your-refresh_token \
-d client_id=your-client-id \
-d client_secret=your-client-secret \
Let me know if the issue persists.
