Running await inside RxJS Observable flatMap
0
I am trying to return an observable inside an async arrow function passed to a flatMap, but the returned observable is not being called.
protected buildUseCaseObservable(params: LoginUserParams): Observable<Session> {
return this.userRepository.getUserByName(params.getUsername())
.pipe(flatMap(async user => {
if (!user) {
throw new Error(Errors.USER_DOESNT_EXIST);
}
const match = await this.cypher.compare(params.getPassword(), user.password);
if (!match) {
throw new Error(Errors.WRONG_PASSWORD);
}
return Observable.create((subscriber: Subscriber<Session>) => {
subscriber.next(new Session("token test", "refreshToken test"));
subscriber.complete();
});
}));
}
Does anyone knows why does it happen and how can I solve it? Thanks in advance.

Solved, I just turned the promise into an observable and did flatMap it.
protected buildUseCaseObservable(params: LoginUserParams): Observable<Session> {
return this.userRepository.getUserByName(params.getUsername())
.pipe(flatMap(storedUser => {
if (!storedUser) {
throw new Error(Errors.USER_DOESNT_EXIST);
}
return from(this.cypher.compare(params.getPassword(), storedUser.password));
})).pipe(flatMap(match => {
if (!match) {
throw new Error(Errors.WRONG_PASSWORD);
}
return Observable.create((subscriber: Subscriber<Session>) => {
subscriber.next(new Session("token test", "refreshToken test"));
subscriber.complete();
});
}));
}
