wip: Working on fixing the CError, commented out the code:

- Commented out all models except the calendar model to fix the C Error
- The error is coming from the dump method in the core_methods file
- The error happen because we call `obj.dump` so, maybe a registered
  model does not implement this method, or there is an issue in any of
  these methods, so i commented out the code to unlock one by one to
  understand the reason of the compiler error
