cpgw's Issues

Decimal is not JSON Serializable with pyzmq==22.2.1

Hello Hardwario Team,

with a new installation of the cpgw, the pyzmq version 22.2.1 was pulled. The socket.send_json(payload) from app.py throws the Decimal not JSON Serializable error. I bypassed the issue by downgrading pyzmq, so it is not blocking, just so you are aware of this issue.
