Uncaught (in promise) TypeError: Cannot read properties of undefined (reading forEach')

This error occurs when you are trying to access a property or method of an undefined value.

In this specific error message, it is saying that you are trying to use the `forEach` method on an undefined value. This means that the variable you are trying to iterate over with `forEach` is undefined.

To fix this error, you need to make sure that the variable you are trying to iterate over is defined and contains the expected value. You can add a check to ensure that the variable is defined before trying to use it, or you can debug your code to see where the variable is being assigned and why it might be undefined.
