How to look at the error that is highlighted in red underlining and remove incorrect errors?

Question

Visual Studio Code

I don’t understand what VS Code doesn’t like (on the screen).
The browser and the error collector does not give out, only the editor highlights, but I don’t understand what.
This does not affect the work of the js script, but it is very annoying when one file is highlighted in red for no reason.
It also does not work to remove these uncorrected errors.
