AsyncStream.from(mongoCursor) TypeErrors

TypeError: Cannot read property 'done' of null

if ( result.done ) {

When writing code of the form

      const results = await AsyncStream.from(cursor)
        .filter(() => true)
        .toArray();

as a workaround, possible to pass the async iterator directly:

      const results = await AsyncStream.from(cursor[Symbol.asyncIterator]())
        .filter(() => true)
        .toArray();
