It seems like the issue is at the \scylla\venv-pipinstall\Lib\site-packages\sanic\response.py file.

change the line to the following temp fixed the issue but the date will not showing correctly:

    return HTTPResponse(dumps(body, **kwargs, default=str), headers=headers,
                        status=status, content_type=content_type)

or need use json_dumps here https://github.com/imWildCat/scylla/blob/master/scylla/web/server.py#L102
