Can you suggest alternative approaches such as using the catchError function or incorporating the use of catchError?

Yes, there are alternative approaches to handle errors in RxJS. One of them is to use the catchError() function. This function catches any errors that occur in the Observable and allows you to handle them in a custom way.

Here's an example of using catchError():

import { catchError } from 'rxjs/operators';

function fetchData() {
  return myObservable.pipe(
    catchError((error) => {
      console.error('An error occurred:', error);
      return of([]);
    })
  );
}

In this example, we import the catchError() function from the RxJS operators, and then use it to catch any errors that occur in the myObservable observable. The catchError() callback function receives the error object and can handle it in any way you like. In this example, we simply log the error and return an empty array.
