nestjs returns 404 not found for 1 routes working fine for others

Question

I am using nestjs to create an API, quite new to it. I created 4 modules and all 4 seem to be working fine. I created another module name steps but all routes I access in it returns 404 not found.

Answer 1

when after add new routes and controllers, we should clean up dist folder and restart yarn start:dev to make sure the added fils work...

Answer 2

perhaps the app uses a global prefix (app.setGlobalPrefix) and it is easy to forget about it when checking new endpoints

Answer 3

Got this trouble using a jwt as a route parameter findByJwt/:jwt with a string "toto" it works, with a jwt nestjs return a 404

Answer 4

Run the following commands when you add new routes and controllers.

yarn run build
yarn start

Answer 5

In my case, the route param contained a hyphen, which NestJS (or Express?) seemed to hate and stuck to return 404.

@Controller('foo/:foo-id')
export class FooController {

  @Get('/')
  async foo() {}
}

After changing the param name to fooId, GET /foo/1 started returning 200.

@Controller('foo/:fooId')
export class FooController {

  @Get('/')
  async foo() {}
}
