# What this PR does
This PR, overrides Django URLValidator with a CustomURLValidator. It
just removes tld_re part from the regex, and the other behaviour remains
the same.
The CustomURLValidator is defined in common.api_helpers.utils.py file
and is utilized in custom_button.py.
Please inform me if it needs to be defined somewhere else or be
implemented with some other methods.
## Which issue(s) this PR fixes
Currently, URLValidator raises exception for URLs that don't have TLD.
This leads to not being able to use containers URL for outgoing webhooks
as they usually don't have TLD.
## Checklist
- [x] Tests updated
- [ ] Documentation added
- [x] `CHANGELOG.md` updated
