VM428:7 Uncaught TypeError: Cannot read properties of null (reading 'CodeMirror') at <anonymous>:7:17

Question

My code is running fine overall, but I keep encountering this error in the browser console:

VM428:7 Uncaught TypeError: Cannot read properties of null (reading 'CodeMirror')
at :7:17

I’m not sure where this error originates or why it’s occurring.

Some context about my setup:

I’m using CodeMirror in my project. The error doesn’t seem to impact the overall functionality but still appears in the console. Can anyone help me understand what might be causing this and how to resolve it?
