title: Unable to create call adapter for retrofit2.Response<...>
body: <p>My Api:</p>
  <pre><code>@GET(&quot;/cinema/notShownMovies&quot;)
  fun getNotShownMovies(
     @Query(&quot;token&quot;) token: String
  ): Response&lt;GetMovieResponse&gt;
  </code></pre>
  <p><strong>Exception when trying to call API:</strong></p>
  <blockquote>
  <p>java.lang.IllegalArgumentException: Unable to create call adapter for
  retrofit2.Response&lt;...data.GetMovieResponse&gt;
  for method InstanceApi.getNotShownMovies Unable to create call adapter for retrofit2.Response&lt;...data.GetMovieResponse&gt;
  for method InstanceApi.getNotShownMovies</p>

  <p>I don't know where to start. All other API calls work fine which is also defined in the same API class. Maybe a model error?</p>
