Current behavior

When editing the Field Rules of a Schema, if any existing Field Rules are present, saving the Field Rules will not work.

Expected behavior

Should be able to save Field Rules.

Minimal reproduction of the problem

  1. Create a new Schema
  2. Add Fields to the Schema
  3. Click on “More” to see the Field Rules section
  4. Add a Field Rule and click on Save
  5. Leave the “More” section (e.g. click on “Fields”)
  6. Go back to the “More” section and try to change the rule or add a new rule, the Save button will not send a request to the server.

The following error in the JS Console appears to be relevant:

ERROR TypeError: Cannot read properties of null (reading '_rawValidators')

I have also recorded a short 3-minute video of me reproducing the issue and showing the console errors and the network requests:


  • [ x ] Self hosted with docker
  • [ ] Self hosted with IIS
  • [ ] Self hosted with other version
  • [ ] Cloud version

Version: 6.4.0


  • [ x ] Chrome (desktop)
  • [ ] Chrome (Android)
  • [ ] Chrome (iOS)
  • [ ] Firefox
  • [ ] Safari (desktop)
  • [ ] Safari (iOS)
  • [ ] IE
  • [ ] Edge


This is already fixed

Oh, great! Do you know when the fix will be released? From what I can tell 6.4.0 is still the latest version?

There is a 6.5.0 afaik, but only on docker. There was an issue with the CI. I want to make a new version end of next week

Ah yes, so there is! Great! I will try it, thanks!
