SMTP mail issue Missing credentials for "PLAIN"

[programmeddeath1]

I have self-hosted affine, and trying to just get the smtp to work for invite mails,

The sending of the mail fails in frontend with

Failed to load resource: the server responded with a status of 500 (Internal Server Error)Understand this errorAI
vendor.77296a2a.js:sourcemap:985 BackendError: Server error: An internal error occurred.

The affine server logs show following error -
