Several optional parameters can be set that control the creation of the JSON strings. Those parameters can be set via GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value and are described in the documentation of write_dictwrite_dictWriteDictWriteDictWriteDictwrite_dict:
