DBE 897 and G2Glink template

Question

Mildenhall-49 shows DBE 897 with the reported error as

invalid format: ^\d{1,7}(/.*): Numbered parameter: 1 (Post number)
{{G2GLink|126584}}

The generated link works and appears valid according to the template page, where a plain number is acceptable as the parameter, but the regex given won't match that. The post-number part is optional so the regex may need to be something like \d{1,7}(/.*){0,1} or (if the slash needs escaping) \d{1,7}(\/.*){0,1}.

Comments

Or for a more robust check

^\d{1,7}(/|$)
