  2. Compare Core database dashboard with other environments - no difference i could see

I just had a similar issue within Sitecore(9.3) forms.

I was building a custom save action and at somepoint, I have faced this same error.

Here is what I did.

I have created a custom save action here : /sitecore/client/Applications/FormsBuilder/Components/Layouts/Actions/ACustomSaveAction

Within this Custom Save action Item, I have multiple items such as :

  • HeaderSubtitle
  • HeaderTitle

Then, I needed an itemTreeView (just like the Redirect to page save action). So I created one by duplicated it, added it to my custom save action's control (from presentation details).

The catch was, I had put this item within another item(of type /sitecore/client/Business Component Library/version 2/Layouts/Renderings/Containers/Expander/Expander Parameter), by trying to create a section with a name. Long story short, anytime this itemTreeView( /sitecore/client/Business Component Library/version 2/Layouts/Renderings/Lists and Grids/ItemTreeView/ItemTreeView Parameters) item was under an item, I got this error. Just had to move this item as a direct child of PageSettings and I was good to go.

My first thoughts were code related, turns out it wasnt. Hope it helps ..!
