I have a textarea in a Fieldset (page), when I had a link to a text I get these warnings (14 times the same): Warning: Attempt to read property "fieldgroup" on null in [...]wire/modules/Process/ProcessPageEditLink/ProcessPageEditLink.module on line 573 Warning: foreach() argument must be of type array|object, null given in [...]wire/modules/Process/ProcessPageEditLink/ProcessPageEditLink.module on line 573 I search but couldn't find anything. Anyone have an idea why these warning?
