section 10-01 실습중에 DB연결 및 생성이 안되서 질문드립니다.

import { ApolloDriver, ApolloDriverConfig } from '@nestjs/apollo';
import { Module } from '@nestjs/common';
import { ConfigModule } from '@nestjs/config';
import { GraphQLModule } from '@nestjs/graphql';
import { TypeOrmModule } from '@nestjs/typeorm';
import { BoardsModule } from './apis/boards/boards.module';

@Module({
  imports: [
    BoardsModule,
    ConfigModule.forRoot(),
    GraphQLModule.forRoot<ApolloDriverConfig>({
      driver: ApolloDriver,
      autoSchemaFile: 'src/commons/graphql/schema.gql',
    }),
    TypeOrmModule.forRoot({
      type: process.env.DATABASE_TYPE as 'mysql',
      host: process.env.DATABASE_HOST,
      port: Number(process.env.DATABASE_PORT),
      username: process.env.DATABASE_USERNAME,
      password: process.env.DATABASE_PASSWORD,
      database: process.env.DATABASE_DATABASE, // env파일에서 수정
      entities: [__dirname + '/apis/**/*.entity.*'], // 수정
      synchronize: true,
      logging: true,
    }),
  ],
})
export class AppModule {}

 위와같이 코드 작성했고

터미널에서 yarn start:dev 할경우

아래와 같이 오류가 떠서 작동이 되지않습니다.

어떻게하면 될까요?
