Cannot read properties of undefined (reading 'config')

This error message typically occurs when you are trying to access a property of an undefined object. In this case, it seems that you are trying to access the 'config' property of an undefined object.

To resolve this issue, you need to ensure that the object is defined before accessing its properties. You can do this by checking if the object exists using an if statement or using optional chaining.

Here's an example of using optional chaining to safely access the 'config' property:

const configValue = object?.config;

In the above code, if the 'object' is undefined, the expression will short-circuit and return undefined, avoiding the error.

Alternatively, you can use an if statement to check if the object is defined before accessing its properties:

if (object) {
  const configValue = object.config;
}

By checking if the object exists before accessing its properties, you can avoid the "Cannot read properties of undefined" error.
