PoET engine error when setting up Docker Sawtooth Network Environment

I'm trying to set up the Docker Sawtooth Network Environment using PoET Simulator (CFT) following these steps: https://sawtooth.hyperledger.org/docs/core/releases/latest/app_developers_guide/docker_test_network.html.

The intkey set transaction works properly in the PBFT network. I can get the key value using inktey show in all REST API containers and a new block is created.

But, with PoET, I don't have any response in log terminal and no block is created. What happens when i try to get key value in any node:

root@e9b57e11feb6:/# intkey set --url http://sawtooth-rest-api-default-0:8008 MyKey 999
{
  "link": "http://sawtooth-rest-api-default-0:8008/batch_statuses?id=35f975022d853deddf0b7329ca8d10e608d3a3fa3e5f2318164e6de738c705e11aa335d709dfda12c50dc807346e8dace2e204cb14ad32699cb2a87b2a6e6f1b"
}
root@e9b57e11feb6:/# intkey show --url http://sawtooth-rest-api-default-1:8008 MyKey
Error: No such key: MyKey

When I started the network with docker-compose up, the following error message appeared:

sawtooth-poet-engine-0          | [2020-12-12 14:28:55.147 ERROR    zmq_driver] Uncaught driver exception

I found these messages in the end of /var/log/sawtooth/poet-engine-debug.log file in the sawtooth-poet-engine-0 container:

Try not to use hyperledger/sawtooth-poet-engine:chime docker image for poet-engine-# containers in sawtooth-default-poet.yaml file.

Change it to hyperledger/sawtooth-poet-engine:nightly to all containers if you are building a network.

If you feel uncomfortable with the nightly version try others(https://hub.docker.com/r/hyperledger/sawtooth-poet-engine/tags) but it seems outdated.

Don't forget to use this command to clear all of the previous block data in docker volume when necessary.

    docker volume rm $(docker volume ls -q)

So, poet-engine doesn't implement PING Message (MessageType=700)
