Why do I get JWTStrategy requires a secret or key with NestJS?

I'm implementing authentication for my NestJS project. I strictly followed the NestJS documentation and this but I still get an error when I try to start the API. I can't seem to figure out what is causing this. I tried setting the secretOrKey to hardcoded string but no to effect then I moved it to a .env still not working.

Below are my code for the module and the JwtStrategy file.

// AuthModule
@Module({
  imports: [
    ConfigModule.forRoot(),
    UserModule,
    PassportModule.register({ defaultStrategy: 'jwt' }),
    TypeOrmModule.forFeature([Registration]),
    JwtModule.register({
      secretOrPrivateKey: process.env.JWT_SECRET_KEY,
      signOptions: { expiresIn: process.env.JWT_EXPIRES }
    }),
  ],
  controllers: [AuthController],
  providers: [AuthService, LocalStrategy, JwtStrategy],
  exports: [AuthService, LocalStrategy, JwtStrategy]
})
export class AuthModule {}

// JWTStrategy
import { Injectable, UnauthorizedException } from "@nestjs/common";
import { PassportStrategy } from "@nestjs/passport";
import { Strategy, ExtractJwt } from "passport-jwt";
import { AuthService } from "./auth.service";

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor(private readonly authService: AuthService) {
    super({
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      passReqToCallback: true,
      secretOrKey: 'test'
    })
  }

  async validate(payload: any, done: Function) {
    const user = await this.authService.validateUserToken(payload)
    if (!user) {
      return done(new UnauthorizedException(), false)
    }

    done(null, user)
  }
}

This is the error I get from the terminal

I figured out the problem, on my local.strategy.ts file instead of importing Strategy class from passport-local it imported from passport-jwt.
