I'm sorry to hear that you're encountering an error. The error message "Cannot read properties of null (reading 'label')" typically indicates that you are trying to access a property called 'label' on a null value. In JavaScript, this error occurs when you try to access a property or call a method on a variable that is null or undefined.
To resolve this issue, you need to make sure that the variable you're trying to access the 'label' property on is not null or undefined. You can do this by checking if the variable is null or undefined before accessing its properties.
Here's an example of how you can handle this error:
```javascript
if (yourVariable !== null && typeof yourVariable !== 'undefined') {
// Access the 'label' property of yourVariable
console.log(yourVariable.label);
} else {
console.log("yourVariable is null or undefined");
}
```
By performing this check, you can avoid the error and handle the situation where the variable is null or undefined in a controlled manner.
