Same here…
This is my stack:
- Strapi: 3.4.5
- Database: Postgres 13
- Node: 14.15.4
and my regex are:
# URL
https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-z]{2,63}\b([-a-zA-Z0-9@:%_\+.~#?&/=]*)
# Email
\b[\w\.-]+@[\w\.-]+\.\w{2,4}\b
I get that same error, and it prevents my content to be saved.
