Cannot read properties of undefined (reading 'default')

This error usually occurs when you are trying to access a property or a method on an undefined or null value. The error message "Cannot read properties of undefined (reading 'default')" specifically suggests that you are trying to access the property 'default' on an undefined object.

To resolve this error, you need to make sure that the object is defined before accessing its properties. You can do this by checking if the object exists using an if statement or by using optional chaining (?.) to handle the undefined case gracefully.

Here's an example of using optional chaining to avoid this error:

const obj = undefined;
const value = obj?.default; // value will be undefined

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

const obj = undefined;
let value;
if (obj !== undefined) {
  value = obj.default;
} else {
  // handle the case when obj is undefined
}

By ensuring that the object is defined before accessing its properties, you can avoid the "Cannot read properties of undefined" error.
