TypeError: Cannot read properties of null (reading 'CodeMirror') , getting this error in the localhost. I dont know why I am getting this error while running in localhost.this keeps popups on localhost.

Expecting a turnaround or a solution to this, this keeps popups on localhost.

The question is a lack of info, anyway If I got u correctly you have to check whether its null or not before u call it

if (CodeMirror !== null){
    CodeMirror()
}

if this some like this sample.user.codeMirror then u can use sample?.user?.codeMirror

CodePudding user response：

try yourObj?.CodeMirror or yourObj.CodeMirror || {}

CodePudding user response：

This is not an Answer !! Please have a look at the image for more info. This error shows up when i enter a text in input field.

CodePudding user response：

CodePudding user response：

same problem today! The problem just appears when i use chrome browser

CodePudding user response：

Hello everyone! Don't worry, we are all having the same error.

I tell you that I was able to solve it, thanks to a comment on this same site that indicated to uninstall all google chrome extensions.

I personally recommend you try uninstalling the "Blackbox - Select. Copy. Paste & Find" extension.

And also the extension of react development tools.

And surely, they will solve the problem in question. Thank you all very much for your contributions.

pdtt: I will write this same comment, both in English and Spanish. In order to reach more people.

Cheers!
