[Bug] r.mess runs on command line but not from Python console

[ecodiv]

Name of the addon
r.mess

Describe the bug
The r.mess works when run from the command line. However, when run from the Python console, it throws an immediate error.

Traceback (most recent call last):
  File "/usr/lib/python3.12/code.py", line 90, in runcode
    exec(code, self.locals)
  File "<input>", line 1, in <module>

    for k, v in env.items():
                ^^^^^^^^^
AttributeError: 'str' object has no attribute 'items'

To Reproduce
Steps to reproduce the behavior:

In the Python console, run e.g.,

gs.run_command("r.mess", env="bio_1,bio_2", output="test_02")

Expected behavior
It should run, as it does on the command line, and generates the mess layers
