OAuth getToken: Invalid Request.

[amit-ksh]

• Trying to get the tokens object from the getToken method but always returning invalid_request

• It's giving status: 400 Bad Request

• Error (in Browser)

• Error (in Terminal)

  Error: invalid_request

  export default async function authorize(

  const { state, code } = req.query as unknown as Record<string, string>;
  
  const { appId } = JSON.parse(state ?? '') as unknown as Record<
  string,
  string
  >;
  
  if (!code || !appId) return res.redirect('/?errorMsg=Server error!');
  
  // Get an access token based on our OAuth code
  const { tokens } = await oAuth2Client.getToken(code);
  
  if (!tokens.access_token || !tokens.refresh_token)
  return res.redirect('/?errorMsg=Server error!');
  
  // Some logic
  
  return res.redirect('/?successMsg=App created successfully!');
  }

await only works in an async function.

Closing this issue: I was not passing the redirectUri to the exported oAuth2Client object.
