Not an email

Error message

Not an email

What it means

During pm2.io / pm2-plus signup or signin, the CLI collects an email and validates it against an RFC-ish regex before sending it to the auth endpoint. A string that doesn't match (no @, bad TLD, embedded spaces) is rejected client-side before any network call.

Solutions

1. Re-enter the email in standard user@host.tld form.
2. Trim leading/trailing whitespace before submitting.

const isEmail = (s) => typeof s === 'string' && /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(s.trim());
if (!isEmail(email)) throw new Error('Please enter a valid email address');

const isEmailLike = (s) => typeof s === 'string' && /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(s.trim());

When it happens

Trigger: Entering a malformed email at the interactive `pm2 plus register` / `pm2 plus login` prompt — missing @, invalid domain, trailing spaces.

Common situations: Typo in the email, copy-paste artifacts, autocorrect, or passing an empty string.
