Hi, I got an error in the end-to-end testing process.
Locally it works fine. However, when I run through GitHub actions, it displays this error:

[Nest] 2787  - 01/20/2023, 5:20:08 PM   ERROR [PackageLoader] The "@nestjs/platform-express" package is missing. Please, make sure to install this library ($ npm install @nestjs/platform-express) to take advantage of NestFactory.

      at Object.<anonymous> (test/app.e2e.spec.ts:15:21)

E2E spec:

  let app: INestApplication;

  beforeAll(async () => {
    const moduleRef = await Test.createTestingModule({
      imports: [AppModule],
    }).compile();

    app = moduleRef.createNestApplication();

    const validationPipe = new ValidationPipe({
      transform: true,
    });

    app.useGlobalPipes(validationPipe);

    await app.init();
  });

Has anyone experienced this failure?

Thanks in advance for the help.

can you show your workflow yaml file?
I've been using GHA just fine

If I use FastifyAdapter and NestFastifyApplication instead, it works fine.

beforeAll(async () => {
  const moduleRef = await Test.createTestingModule({
    imports: [AppModule],
  }).compile();

  app = moduleRef.createNestApplication<NestFastifyApplication>(
    new FastifyAdapter(),
  );

  const validationPipe = new ValidationPipe({
    transform: true,
  });

  app.useGlobalPipes(validationPipe);

  await app.init();
  await app.getHttpAdapter().getInstance().ready();
});

#

first of all, choose one adapter

#

it would be express or fastify?

can you run npm ls express

#

I mean, yarn why express

#

looks fine

#

have you tried yarn --cwd "./packages" install locally?

torpid lake
crisp sluice
#

add one step to run yarn why express in your workflow along with working-directory: ./packages/cats

torpid lake
#

ok i will try that

#

same error

crisp sluice
#

that's not for solving the error, it's for debugging

#

which output did you got

#

mine looks like this
