Hey Ben Hamida,
This forum is meant for more general high level discussion of the platform and services, design patterns, etc. This is a question which belongs on
Stack Overflow, although it is also lacking the details which would be required in a question there. When asking for technical assistance, you should provide some minimal details about what's happening, what you have done, etc. Please be sure to provide the following information when you post to Stack Overflow:
* Where did you get the library from?
* How did you build the skeleton for your project?
* Which cloud database are you using?
* What error did you see?
This information should be enough to enable somebody on Stack Overflow to start helping you to troubleshoot. Once you've made the post there, you can link it here and I'll be happy to follow up in the appropriate forum.
Cheers,
Nick
