Thanks for your help. I did it and it now recognize the invalid regex, but now I’m having issues with the length.
This is are the rules:
If i send “Mi Super Empresa <<” which has 19 letters I’m getting the error ‘max validation failed on short_name’, error that I don’t have with 20 normal letters. If I take out the sanitization rule the validation runs ok.
As my regex is more restricted than ‘escape’ I’ll take out the sanitization rule, but the issue is there.
Again, thanks for your help!
