NSwag: Duplicate function implementation while creating restful service.

Hi, I’m trying to create my service as restful, but when I run Refresh.bat file and run npm start. It gives errors.

[Route("api/services/app/Test")]
[HttpPost]
public async Task CreateTest(TestDetailsDto input)

[Route("api/services/app/Test")]
[HttpDelete]
public async Task DeleteTest(EntityDto input)

[Route("api/services/app/Test")]
[HttpGet]
public async Task GetTest(EntityDto input)

[Route("api/services/app/Test")]
[HttpPut]
public async Task UpdateTest(TestDetailsDto input)

Errors:
