Error in mounted hook TypeError Cannot read properties of undefined reading addEventListener

This error message suggests that there is an issue within the mounted hook of your code, specifically with trying to access an event listener on an undefined object.

To fix this issue, you should check that all necessary objects and variables are defined before trying to access their properties. You may also want to review the code inside the mounted hook to ensure that it is properly structured and that you are not trying to access properties that do not exist.
