Have invalid grant error

See original GitHub issue

Error: invalid_grant
    at createError (/user_code/node_modules/googleapis/node_modules/axios/lib/core/createError.js:16:15)

I first get the authenticationCode in front end using gapi.auth2.getAuthInstance().grantOfflineAccess() and send the code to server side (server side is firebase cloud functions)

and in server side, I tried like following.

const oauth2Client = new google.auth.OAuth2(
  "XXX",
  "XXX",
  "XXX"
);

oauth2Client.getToken(authenticationCode)  // authenticationCode  is from front end

When I got the error. Any idea how to fix it?

I’m having this same problem right now. My front-end is running with ReactJS to get code token (GAPI).

window.gapi.load('auth2', function() {
  window.auth2 = window.gapi.auth2.init({
    client_id: OAUTH2_CLIENT_ID,
    scope: OAUTH2_SCOPES
  });
});

window.auth2.grantOfflineAccess().then((code) => console.log(code));
// Returns -> { code: 'XXXXXX...XXXX' }

In my Express server I run the googleapis to get token, but not working.

const code = { code: 'XXXXXX...XXXX' };
const OAuthClient = new OAuth2(
  ID,
  SECRET,
  REDIRECT
);

OAuthClient.getToken(code, (error, tokens) => {
  if (error)  return console.log(error);

  OAuthClient.setCredentials(tokens)
});

Error data:

data: { error: 'invalid_grant', error_description: 'Bad Request' }
