Uncaught TypeError: Cannot read properties of null (reading 'addEventListener')

my project work fine I test as locallhosr server, but when I update my site I got this error Uncaught TypeError: Cannot read properties of null (reading ‘addEventListener’)

@salehalrsh That’s a fairly standard JavaScript error and unlikely to be related to hosting on Netlify.

Just debug your code, click on the error in your developer console, see where it’s occurring.

Whatever the .addEventListener is on is null and you would fix your code as necessary.
