consumer.fetch() return type is not properly exported

[shadone]

Observed behavior

When calling consumer.fetch() the returned value becomes of any type.

I see that the consumer.fetch() is defined to return Promise<ConsumerMessages> in jetstream/src/types.ts and ConsumerMessage is defined as QueuedIterator<JsMsg>

export type ExportedConsumer = ConsumerKind & {
    fetch(opts?: FetchOptions): Promise<ConsumerMessages>;
};

export type ConsumerMessages = QueuedIterator<JsMsg> & Close & {
    status(): AsyncIterable<ConsumerNotification>;
};

However when importing @nats-io/jetstream in my code, the return value of consumer.fetch() gets erased to any, see attached screenshots from my IDE

Expected behavior

The return value of consumer.fetch() should be "ConsumerMessages"

Server and client version

@nats-io/jetstream version 3.2.0

Host environment

The same issue happens with Consume, it seems it can't get the QueuedIterator and falls back to any

[mpeterdev]

I am temporarily getting around this by reconstructing the type in my code as ConsumerMessagesProxy and manually applying that to messages

import {
  type Close,
  type ConsumerNotification,
  type JsMsg,
  jetstream,
} from '@nats-io/jetstream';
import type { QueuedIterator } from '@nats-io/nats-core';
import { connect } from '@nats-io/transport-node';

type ConsumerMessagesProxy = QueuedIterator<JsMsg> &
  Close & {
    status(): AsyncIterable<ConsumerNotification>;
  };

async function example() {
  const nc = await connect({ servers: ['nats://localhost:4222'] });
  const js = jetstream(nc);
  const consumer = await js.consumers.get('test');
  const messages: ConsumerMessagesProxy = await consumer.fetch();
  for await (const msg of messages) {
    console.log(msg);
  }
}
