我有麻烦与使用 Mongoose 在巢
错误消息如下：
Nest无法解析movieModel（？）的依赖项。请确保索引[0]处的参数DatabaseConnection在MongooseModule上下文中可用。
潜在的解决方案：

• 如果DatabaseConnection是一个提供者，它是当前MongooseModule的一部分吗？
• 如果DatabaseConnection是从一个单独的@Module导出的，那么该模块是否在MongooseModule中导入？

movies.service.ts

import { Injectable } from '@nestjs/common';
import { CreateMovieDto } from './dto/create-movie.dto';
import { InjectModel } from '@nestjs/mongoose';
import { movie, movieDocument } from './schema/movie.schema';
import { Model } from 'mongoose';

@Injectable()
export class MoviesService {
  constructor(
    @InjectModel(movie.name) private movieModel: Model<movieDocument>,
  ) {}

  async create(CreateMovieDto: CreateMovieDto): Promise<movie> {
    return new this.movieModel(CreateMovieDto).save();
  }

  async getAll(): Promise<movie[]> {
  return this.movieModel.find().exec(); 
  }

app.modules.ts

import { Module } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { MoviesModule } from './movies/movies.module';

@Module({
  imports: [
    MoviesModule,
    MongooseModule.forRoot('mongodb://localhost:27017/databasename', {
      connectionName: 'movies',
    }),

请帮我弄清楚
