I've written a Google Apps Script web app to allow users to change their gmail signature using a html form template via the Gmail API. This has been working for a few months but has suddenly stopped working. The console error I get is:
mae_html_user_bin_i18n_mae_html_user.js:40 Uncaught Error: Missing required scope "https://www.googleapis.com/auth/gmail.settings.basic" for modifying primary SendAs
at setSignature (Code:151) (Email Signature Generator:21)
This error refers to the use of this line of code:
Gmail.Users.Settings.SendAs.patch(newSig, "me", Session.getActiveUser().getEmail());
SendAs.patch requires the following authorization:
https://developers.google.com/gmail/api/v1/reference/users/settings/sendAs/patch
https://www.googleapis.com/auth/gmail.settings.basic
https://www.googleapis.com/auth/gmail.settings.sharing
After deleting the previously stored permissions and re-running the app the authorization window lists the following permissions:
Note that "Manage your basic email settings" (gmail.settings.basic) is missing. So, what am I doing wrong? Can I rectify this, or is this a gmail-api auth bug?
According to https://developers.google.com/apps-script/guides/services/authorization :
Apps Script determines the authorization scopes (like access your Google Sheets files or Gmail) automatically, based on a scan of the code. Code that is commented out can still generate an authorization request. If a script needs authorization, you'll see one of the authorization dialogs shown here when it is run.
Is there any way to manually request an auth permission?
