A method handler is interfering into another handler with same name in another controller.

Bug Report

Current behavior

I had two controllers into two differnt folders and differnt modules, Both of them has a method with same create name.

/admin/entity.controller.ts

    @Controller("admin")
    export class EntityController{
        @Post()
        public async create(@Request() request: any): Promise<List> {
            console.log("request", request) // Logs the Body {"name": "test"} instead of request.
        }
    }

/user/entity.ontroller.ts

    @Controller("user")
    export class EntityController{
        @Post()
        public async create(@Body() entity: Entity) {
            console.log("entity", entity) // logs the body {"name": "test"}
        }
    }

When I do post the following in both routes: {"name": "test"},

curl -X POST http://localhost:3000/admin/ -d '{"name":"test"}'

curl -X POST http://localhost:3000/user/ -d '{"name":"test"}'

It happens that admin create() method logs the body part, not the requests as expected.

It seems to be that the definition of the user controller is interfering into the admin controller and making it to do not work properly.

Environment

• Nest version: 6.0.0
• Node version: v10.15.1
• Platform: Windows 10

Fixed in 6.6.0 :)

@kamilmysliwiec @daniel-dia The problem is only partially fixed. There is a very similar bug with global pipes. When 2 controllers with the same name and method are used public async transform(value: any, metadata: ArgumentMetadata) method of pipes receives incorrect ArgumentMetadata for the second method.

As a result if you use pipe-based validation with for example ValidationPipe you are in trouble. The bug is still present in 6.6.3.
