I have been trying to get nodemailer to deliver rsvp responses to my email with the help of Oauth2. I had short term success but then realized the access token needed to be refreshed constantly for Oauth2 to continue to work. So after trying suggestions from here:
Google oauth 2.0 API password change Username and Password not accepted
...and following steps from here: https://medium.com/@nickroach_50526/sending-emails-with-node-js-using-smtp-gmail-and-oauth2-316fe9c790a1
...I have found myself stuck with this unhandled promise rejection error:
(node:42384) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
I don't know what else to try. I've been searching for help for weeks. Does anyone know how to fix this error? I appreciate any help offered. Thanks.
