Getting "Cannot read properties of null (reading 'nodeType')" when trying to do cntl+A, cntl+c and cntl+v

[Rsi-madhuri]

Bug Description

When trying to do cntl+A, cntl+c and cntl+v in proseMirror editor. It is showing error- Cannot read properties of null (reading 'nodeType').

This is happening when I have header content which is non-editable and main content which is editable. When I try to do cntl+A, cntl+c and cntl+v. It is selecting only main content which is expected but throwing above error.

The issue is coming from prosemirror-model/dist/index.js file where inside renderSpec function where in line no 3393
if (structure.nodeType != null)
return { dom: structure };
here structure is coming as null.

Browser Used

Chrome

Expected Behavior

When we do cntl+A, cntl+c and cntl+v, all selected text should be copied and pasted in editor instead of throwing error.

here structure is coming as null.

That might be coming from your code. Have you tried reducing this to the minimal code needed to trigger it?
