Error: Unable to access property 'addEventListener' of null. This issue appears to be related to a Chrome extension

It's been frustrating dealing with this persistent error. I'm in the process of creating my very first chrome extension and for some reason, I just can't seem to pinpoint what's wrong with this particular code snippet:

let beginButton = document.getElementById("BeginBtn")
beginButton.addEventListener("click", function(){ //this is where the error pops up
    let recognition = new SpeechRecognition()
    recognition.begin()  
})

Answer №1

The error indicates that the startbutton object is null, which suggests there may be a mistake in the identifier
