TypeError: Cannot read property 'play' of null - JavaScript Error Solution

It seems that there is an error in the code. The code is trying to access the 'play' property of an object, but the object is null. This means that the object has not been initialized or it has been set to null.

To fix this error, you should check if the object exists before accessing its properties. You can use an if statement to check if the object is null or undefined before attempting to access its properties. For example:

if (object != null) {
    object.play();
}

This will prevent the error from occurring if the object is null.
