Not able to connect to the server from python.

[joseajunior]

I create a server using a Docker Compose like this:

    image: icr.io/informix/informix-developer-database
    tty: true
    ports:
      - "9088:9088"
    environment:
      DBA_USER: wexrobotlib_user
      DBA_PASSWORD: Passw0rd
      LICENSE: accept
      INIT_FILE: informix_setup.sql
    privileged: true
    volumes:
      - ./INFORMIX_setup.sql:/opt/ibm/config/informix_setup.sql
    healthcheck:
      test: ["CMD", "bash", "-c", "echo \"select count(*) from systables\" | dbaccess sysmaster"]
      interval: 1m30s
      timeout: 30s
      retries: 5
      start_period: 30s

After the creation, I try connecting from the DBeaver with these credentials and it works:

User: wexrobotlib_user
Password: Passw0rd

But If I try to connect using python from the library sqlalchemy and sqlalchemy-informix using this url:
informix://wexrobotlib_user:Passw0rd@localhost:9088/test
or with the authentication value:
informix://wexrobotlib_user:Passw0rd@localhost:9088/test;AUTHENTICATION=SERVER
I get hanged with this error:
[email protected]:1556: err = -408: oserr = 0: errstr = from _gateway to server informix : Invalid message type received from the sqlexec process.
