Error when Restructuring fields

[ReneReiterer]

I just enabled the override shared fields feature and got the message "Restructuring of fields needed!". When i click on the buton "Restructure Mask definitions" nothing happens. When i look in the console i get this error

When i open the link Mask is trying to call in another tab i get this typo3 error:

i am running Typo3 v12.4.4 with Mask version 8.2.6

Updating to 8.3.1 doesnt fix the error

Hi Rene, thanks for trying out the new feature. Could you send me your json file(s), so I can debug it locally?
