Description
Swagger Codegen not working.
Swagger Codegen fails to build ApiClient when response is a Map with some user-defined class and no other api endpoint.
@GetMapping("/cars")
public Map<String, List<Car>> getCars(){
// some code
}
To fix this I had to add another api endpoint with
@GetMapping("/car")
public List<Car> getCar(){
// some code
}
Swagger-codegen version
Swagger Code gen version is 2.3.1

Research direction
Reproduce the Swagger Codegen 2.3.1 failure with the shown Map<String, List> response and no other endpoint, then compare it with the added List endpoint case. Trace the generated ApiClient output and confirm that generation succeeds for the Map response without requiring an unrelated endpoint.
