    isn’t debug showing you more informations on the ‘Send a Test Email’ page?
    Below should be sth stated like:

    Error while sending via Gmail mailer: {
    "error": {
    "errors": [
    "domain": "global",
    "reason": "failedPrecondition",
    "message": "Bad Request"
    "code": 400,
    "message": "Bad Request"

    Here is a short overview about error codes:
    Hope this helps you figure out the reason for your error.

    Best of luck,
