Uncaught TypeError: Cannot read properties of undefined (reading 'style')

This error occurs when you are trying to access the `style` property of an undefined object. The `undefined` value means that the object has not been initialized or does not exist.

To fix this error, you need to check if the object exists before accessing its properties. For example:

if (myObject !== undefined) {
   // Access myObject.style here
}

Alternatively, you can use the optional chaining operator `?.` to access the `style` property only if the object is defined:

const myStyle = myObject?.style;

Using the optional chaining operator can help avoid errors like this one by returning `undefined` instead of throwing a TypeError when the object is undefined.
