Unable to save entity, properties: Type cannot be null

This error occurs when I try to save an object.

Hi Denys,

Please, provide us more information:

  • what version of what SDK do you use
  • the example of code
    Regards Ilya

Maybe the problem happens because some properties of saving object are null?


public <T> void save(T entity, final IResultCallback<T> callback) {
    Backendless.Persistence.save(entity, new AsyncCallback<T>() {
        public void handleResponse(T response) {


        public void handleFault(BackendlessFault fault) {


BE version: com.backendless:backendless:3.0.11
