> Errors are handled multiple ways in the
>  * throwing PythonScriptException
>  * throwing PyException
>  * setting PyErr_SetString
> The error handling should be revised. In case of the minifi_native python module we should probably set the error with PyErr_SetString instead of throwing exceptions that would result in throwing exception in python instead of the c++ code. We should focus on having better error messages and tracebacks in the logs in case of an error to be able to identify the source of the error.
