Im trying to code a “Template”-Service for my TypeORM tables, but i cant manage the errors like i want.

I tried something like this:

My TableService:

import { DeleteResult, FindOptionsWhere, Repository } from "typeorm";
import { Observable, catchError, from, map, throwError } from 'rxjs';


export class TableService<E, PKs> {
    constructor(
        private repository: Repository<E>
    ){}

    delete(primKeys: PKs): Observable<DeleteResult> {
        if (Object.keys(primKeys).length === 0) {
            return throwError(() => new Error('No primKeys set.'));
        } else {
            try{
                return from(this.repository.delete(primKeys as FindOptionsWhere<E>)).pipe(
                    map((delRes: DeleteResult) => { return delRes; }),
                    catchError((err) => {
                        console.log("In catchError");
                        return throwError(() => new Error("err.message"));
                    })
                );
            } catch(err){
                console.log("outer chatch");
            }
            
        }
    }
    
}

The requests are working, if the Query-Params are correct.

But the error handling is not working as i expected.

The error is not caught in catchError, but rather in the outer catch.

I dont understand why…
