'Error when login to Docker container using Molecule

I have this Molecule configuration:

---
dependency:
  name: galaxy
driver:
  name: docker
platforms:
  - name: instance1
    image: docker.io/pycontribs/centos:8
provisioner:
  name: ansible
verifier:
  name: ansible

I run molecule converge and it works fine. Now, I need to log into the instance1 container. When I run molecule login --host instance1, I get this error:

FileNotFoundError: [Errno 2] No such file or directory: '/usr/bin/env docker exec -e COLUMNS=108 -e LINES=41 -e TERM=bash -e TERM=xterm -ti instance1 bash'

What is happening?

Versions

docker package: 5.0.3

molecule: 3.6.1

molecule-docker: 1.1.0

NOTE

If I run the command that is getting an error:

/usr/bin/env docker exec -e COLUMNS=108 -e LINES=41 -e TERM=bash -e TERM=xterm -ti instance1 bash

in a terminal, it works fine.

Solution 1:[1]

This is a known issue with molecule not correctly expanding the shell arguments and has been fixed in this pull request: https://github.com/ansible-community/molecule/pull/3468

I've patched this pull request into my local molecule instance and can confirm it fixes this.
