TypeError Cannot read properties of undefined reading call

This error occurs when you try to call a function on an undefined value.

For example, if you try to call a method on an undefined variable like this:

let obj;
obj.callMethod();

You will get the "TypeError: Cannot read properties of undefined (reading 'call')" error because obj is undefined and doesn't have a callMethod property.

To fix this error, you need to make sure that the variable you're trying to call a method on is defined and has the expected properties.
