'query' does not exist in type 'QueryFn' about base-chat HOT 7 CLOSED

firstly it's need to be together
//import { AngularFireDatabase, FirebaseListObservable } from 'angularfire2/database-deprecated';

secondly it's my funcshion

getMessages(): FirebaseListObservable<ChatMessage[]> {
// query to create our message feed binding
return this.db.list('message', {
query: {
limitToLast: 20
}
});
}

and it's work now.

For AngularFire version 5 and up use,

db.list('/items', ref => ref.orderByChild('size').equalTo('large'));

I'm getting the same issue Argument of type '{ query: { limitTolast: number; orderByKey: boolean; }; }' is not assignable to parameter of type 'QueryFn'.
Object literal may only specify known properties, and 'query' does not exist in type 'QueryFn'.

ERROR in src/app/services/chat.service.ts(55,39): error TS2345: Argument of type '{ query: { limitToLast: number; }; }' is not assignable to parameter of type 'FirebaseListFactoryOpts'.
Types of property 'query' are incompatible.
Type '{ limitToLast: number; }' is not assignable to type 'Query'.
Property 'endAt' is missing in type '{ limitToLast: number; }'.
whats happening??

chat.services.ts

getMessages(): FirebaseListObservable<ChatMessage[]> {
// query to create our message feed binding
return this.db.list('messages', {
query: {
limitToLast: 20,

    }
  });
