This error message typically occurs when you try to access a property or method of an object that is undefined. The error message suggests that the 'root' property is undefined.
To fix this issue, you need to ensure that the object you are trying to access the 'root' property from is properly defined. You can do this by checking if the object exists before trying to access its properties. For example, you can use an if statement to check if the object is defined:
```javascript
if (myObject && myObject.root) {
// Access the 'root' property here
} else {
// Handle the case when 'root' is undefined
}
```
By adding this check, you can prevent the error from occurring and handle the case when the 'root' property is undefined.
