Error 401 with message"The client with clientId \"undefined\" was not found"

[giacomoRanieri]

Trying to setup an oauth service with a mongodb orm setup, there's a problem in the query parameter name mapping.
You can find an example causing the problem in this zip.
oauth-service.zip
Node version: v12.16.1

Test call:

POST http://localhost:3000/oauth2/token?grant_type=password&client_id=6ab1cfab-0b3d-418b-8ca2-94d98663fb6f&client_secret=6nV9GGm1pu8OY0HDZ3Y7QsVnxtkb60wu&scopes=carma&username=j.doe@change.me&password=changeme

Looking into swaggerUI the parameter seems to use the name definedas class member and not the one defined in the decoration.

Can you help me sort the problem?

Thanks,Giacomo

Hi,
Yes I've figure out this... I did not update the doc yet, but you need to set up the application's global pipe with the transform value set to true.

app.useGlobalPipes(new ValidationPipe({
    transform: true,
  }));
