I am using @nestjs/axios in my NestJS backend application to call an endpoint as bellow:

this.httpService.get('some url').pipe(
  catchError(e => {
    throw new InternalServerErrorException('error');
  }),
  map(res => {
    console.log('succeeded');
  })
);

The problem is that when the endpoint is available then the succeeded will be reached, but when the endpoint is not available the catchError is never reached and succeeded neither.
