MinPath12hmp.py generates an error and Pathways are not created

Dear developers and users,

I am using the new ver of HUMAnN3 (v3.9) coupled with MetaPhlan4 (v4.1.1).
For humann I am using chocophlan.v201901_v31 and uniref90_201901b dbs, and for metaphlan the latest vJun23 db.

HUMAnN3 generates an error on every run, only the genefamilies output is created.
The error is in MinPath script (in short):

humann.utilities - CRITICAL: Error executing: /home/ubuntu/mambaforge/bin/python3.10 /home/ubuntu/mambaforge/lib/python3.10/site-packages/humann/quantify/MinPath12hmp.py ...
humann.utilities - CRITICAL: TRACEBACK:
Traceback (most recent call last):
  File "/home/ubuntu/mambaforge/lib/python3.10/site-packages/humann/utilities.py", line 759, in execute_command
    p = subprocess.check_call(cmd, stdin=stdin, stdout=stdout, stderr=stderr)
  File "/home/ubuntu/mambaforge/lib/python3.10/subprocess.py", line 369, in check_call
    raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: ... returned non-zero exit status 1.

Is there some problem with compatibility between some of the dbs I am using? I am feeding HUMAnN3 the species profile obtained from MetaPhlan4.
As far as I understand the problem is in metacyc pathways creation, and those dbs are not directly related to it.

Any help will be appreciated!
