invalid domain

Error message

invalid domain: ${domain}

What it means

Contract validation error from normalizeDomain: after plain-text normalization, lowercasing, stripping a leading 'www.' and trailing dot, the domain entry does not match the DOMAIN pattern. The invalid value is echoed in the message to help locate the bad row.

Solutions

1. Send a well-formed domain like 'example.com' (no scheme, path, or 'www.' prefix needed)
2. Remove the trailing dot and any protocol prefix before submitting
