Question How to find error in code text?

Hi there!

I really want to know how to finding an error section, if it have an error red text in console
basically I used to double click on error red text and it push me directly to the error part of code
But now if I have an error red text and double click again.., it won't go directly to error part at all.
I don't know why...

anyone have this issue like me? please advice me

Thanks!!!
