Steps to reproduce

1. Use a plain Magnolia 6.2.16
2. Create some page (Basic template in my example)
3. Add any component with a translatable field
4. Close pages app
5. Reopen pages app
6. Click on component
7. Check error in log (see attachment)

Expected results

No error should appear.

Actual results

There is a weird error in the log file.

Workaround

Maybe it would be possible to disable the "HasI18nItemRule" on component level. But i did not check that one.

Development notes

I exported the site configuration and my website to check the error quickly.

I also attached the error log.
