Why is the throwError operator depreciated?

[mlc-mlapis]

The operator throwError allows you to return any object you want. When its depreciation was announced, the recommended alternative was new Error('.....'), but it means that only a string can be returned. Am I the only one who needs to return a more structured error, like {errorCode: ..., errorMessage: ..., metadata: ...}?

Only the overload where the error object is passed directly has been deprecated.

-throwError(new Error())
+throwError(() => new Error())
   .subscribe({
     error: (error) => {
       console.log(error);
     }
   });

Ops, thanks. It hasn't been clear from the first moment.
