Channel config cannot be updated: "Error: Invalid channel create transaction : empty channel id"

[mhw0]

Description

Hi. Followed all the steps in this page: https://hyperledger-fabric.readthedocs.io/en/latest/config_update.html#step-1-pull-and-translate-the-config but when it comes to updating the config using the command peer channel update -c default-channel -f config_update_in_envelope.pb, I'm getting "Error: Invalid channel create transaction : empty channel id"

At first, my configtxlator and peer versions were not the same so I downloaded configtxlator from the release 3.0, but no luck.

Updated only max_message_count from 50 to 100 in the config.

Steps to reproduce

1. Run a network with fabric 3.0
2. Follow these steps: https://hyperledger-fabric.readthedocs.io/en/latest/config_update.html#step-1-pull-and-translate-the-config

@mhw0 Are you running fabric 3.0 samples on docker ? Also, kindly confirm if you are running the samples given by hyperledger github.
