JobApi Accept bug

[upling]

public okhttp3.Call getRenderedFormCall(String id, final ApiCallback _callback) throws ApiException {
    Object localVarPostBody = null;

    // create path and map variables
    String localVarPath = "/task/{id}/rendered-form"
        .replaceAll("\\{" + "id" + "\\}", localVarApiClient.escapeString(id.toString()));

    List<Pair> localVarQueryParams = new ArrayList<Pair>();
    List<Pair> localVarCollectionQueryParams = new ArrayList<Pair>();
    Map<String, String> localVarHeaderParams = new HashMap<String, String>();
    Map<String, String> localVarCookieParams = new HashMap<String, String>();
    Map<String, Object> localVarFormParams = new HashMap<String, Object>();

    final String[] localVarAccepts = {
        "application/xhtml+xml", "application/json"
    };
    final String localVarAccept = localVarApiClient.selectHeaderAccept(localVarAccepts);
    if (localVarAccept != null) {
        localVarHeaderParams.put("Accept", localVarAccept);
    }

    final String[] localVarContentTypes = {

    };
    final String localVarContentType = localVarApiClient.selectHeaderContentType(localVarContentTypes);
    localVarHeaderParams.put("Content-Type", localVarContentType);

    String[] localVarAuthNames = new String[] {  };
    return localVarApiClient.buildCall(localVarPath, "GET", localVarQueryParams, localVarCollectionQueryParams, localVarPostBody, localVarHeaderParams, localVarCookieParams, localVarFormParams, localVarAuthNames, _callback);
}

   final String localVarAccept = localVarApiClient.selectHeaderAccept(localVarAccepts);  always return "applicaiton/json"  but  RenderedFormCall content is not a json
