I have this regex that matches 0 or more rows of key/value pairs: https://regexr.com/870pr

However, I’m not succeeding in getting the correct behavior for the validation on the textarea in the backoffice. I have tried these syntaxes (and probably more) but none seem to work:

((\w|\d)+::.+\n?)*
/((\w|\d)+::.+\n?)*/
/^(\w|\d)+::.+\n*$/gm

I have also failed in finding any documentation for custom validations in the Heartcore backoffice.

Can anyone point me in the right direction?

Thanks
