@nancat6 Hello there! I'm a bot designed to help you solve bugs, answer questions, and become a contributor. I'm here to assist you while waiting for a human maintainer.

The result variable has been changed from a boolean type to a numeric type in version 0.6.16 because the current version does not support boolean types. This is indicated by the commented-out code in the _transform_result method:

# TODO: bool is not supported in the current version
# elif parameter.type == 'bool':
#     if isinstance(result[parameter.name], bool):
#         transformed_result[parameter.name] = bool(result[parameter.name])
#     elif isinstance(result[parameter.name], str):
#         if result[parameter.name].lower() in ['true', 'false']:
#             transformed_result[parameter.name] = bool(result[parameter.name].lower() == 'true')
#     elif isinstance(result[parameter.name], int):
#         transformed_result[parameter.name] = bool(result[parameter.name])

Additionally, the integration tests for the CodeNode class in the test_code.py file show that the result variable is expected to be of type number or string, but not boolean [1][2].
