Trying POST without any organ using Retrofit with GSON parsing error

I integrate with the REST API, so I use Retrofit. I need to click the URL:

Http: // {{server}} / API / v1 / material / {{ID}} / deactivate

I created an interface that implements the API:

@PUT("/api/v1/stuff/{id}/deactivate")
String deactivate(@Path("id") String id);

The problem is that I call the method that it fails with the following stack trace:

E/AndroidRuntime( 3046): Caused by: retrofit.converter.ConversionException: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 15

I believe that this is due to the fact that I do not publish anything in the body. What is the best way to get around this?

Note. I have successfully used POSTMan to call the API.
