Fix for "Nest can't resolve dependencies of the MovieService." - nestjs

Question

I keep getting this error but don't know why. If anyone could help me solve it, that would make my day 😁
Error: Nest can't resolve dependencies of the MovieService (?). Please make sure that the argument MovieRepository at index [0] is available in the MovieService context.
This is the structure of my MovieService:
import {Injectable} from "#nestjs/common";
import {InjectRepository} from "#nestjs/typeorm";
import {Repository} from "typeorm";
import {CreateMovieDto} from "./dto/create-movie.dto";
import {Movie} from "./movie.entity";
#Injectable()
export class MovieService {
constructor(
#InjectRepository(Movie)
private readonly movieRepository: Repository<Movie>
) {}
create(createMovieDto: CreateMovieDto): Promise<Movie> {
const movie = new Movie();
movie.path = createMovieDto.path;
movie.title = createMovieDto.title;
movie.originalTitle = createMovieDto.originalTitle;
movie.poster = createMovieDto.poster;
movie.descr = createMovieDto.descr;
movie.year = createMovieDto.year;
return this.movieRepository.save(movie);
}
async findAll(): Promise<Movie[]> {
return this.movieRepository.find();
}
findOne(id: string): Promise<Movie> {
return this.movieRepository.findOne(id);
}
findByPath(path: string): Promise<Movie> {
return this.movieRepository.findOne({path});
}
async remove(id: string): Promise<void> {
await this.movieRepository.delete(id);
}
}
The MovieModule :
import {Module} from "#nestjs/common";
import {TypeOrmModule} from "#nestjs/typeorm";
import {Movie} from "./movie.entity";
import {MovieService} from "./movie.service";
#Module({
imports: [TypeOrmModule.forFeature([Movie])],
providers: [MovieService],
exports: [MovieService],
})
export class MovieModule {}
The Movie entity :
import {Column, Entity, PrimaryGeneratedColumn} from "typeorm";
#Entity()
export class Movie {
#PrimaryGeneratedColumn()
id: number;
#Column()
path: string;
#Column()
title: string;
#Column()
originalTitle: string;
#Column()
poster: string;
#Column()
descr: string;
#Column()
year: string;
}
And the app module :
import {Module} from "#nestjs/common";
import {TypeOrmModule} from "#nestjs/typeorm";
import {AppController} from "./app.controller";
import {AppService} from "./app.service";
import {MovieModule} from "./movie/movie.module";
#Module({
imports: [
TypeOrmModule.forRoot({
type: "mysql",
host: "localhost",
port: 3306,
username: "*****",
password: "*****",
database: "*****",
autoLoadEntities: true,
synchronize: true,
}),
MovieModule,
],
controllers: [AppController],
providers: [AppService],
})
export class AppModule {}
Edit 1
I tried copy-pasting the movie folder into a new nest project and it works. I'm even more confused on why I get this error

Answer 1

I solved my problem. I messed up my imports/exports in some of the files of the project and after double-checking them it worked.
