Current behavior

When setting setGlobalPrefix('v2') and using the Swagger module as described in the doc with SwaggerModule.setup('api', app, document), the API is actually available under /api and /v2/api throws a 404 Cannot GET /v2/api.

It works when setting SwaggerModule.setup('v2/api', app, document), but this introduces duplication.

Expected behavior

I expected the global prefix to be applied to the Swagger module’s path, too.

Minimal reproduction of the problem with instructions

Repro repo. Created with the CLI, only added swagger module as described in the doc and setGlobalPrefix().

Environment

Nest version: 5.0.1

Just tried to reproduce this issue and for me, everything is working correctly. My code:

app.setGlobalPrefix('v1');
const options = new DocumentBuilder()
  .setBasePath('v1')
  .build();

@renatogbp try to change operations order.

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.setGlobalPrefix('api');

  const options = new DocumentBuilder()
    .setTitle('Example')
    .setDescription('The API description')
    .setVersion('1.0.0')
    .build();
  const document = SwaggerModule.createDocument(app, options);
  SwaggerModule.setup('swagger', app, document);

  await app.listen(3000);
}
