This is a simplification of a complex case, where some observables in array could be filtered if the values are not valid. The problem is that the filtered observable is not allowing to the other complete the combine. What operator or approach could handle this case allowing the valid data log in the subscription?

```
// RxJS v6+
import { fromEvent, combineLatest, of } from 'rxjs';
import { mapTo, startWith, scan, tap, map, filter } from 'rxjs/operators';

const userData$ = [
   of({ name: 'Joseph', age: 23}), 
   of({ name: 'Mario', age: 33}), 
   of({ name: 'Robert', age: 24}), 
   of({ name: 'Alonso', age: 25})
];

const names = ['Joseph', 'Mario', 'Robert', 'Alonso'];

combineLatest(
  names.map((name, i) => {
     return userData$[i].pipe(
         map(({name, age})=> { return{ name, age: age * 2} }),
         filter(({age}) => age < 67),
         map(({name, age})=> { return{ name: name.toLocaleUpperCase(), age} }),
     )
 })
)
   .pipe(
     tap(console.log),
   )
   .subscribe();

```

If we change the value to 67 all the observables will show the data.
