progress_displayers.py exception in 0.5.4

[jamesformedix]

I'm trying to test out the newest version of the engine (0.5.4) but every time I run a validation I'm getting the same error. I was previously using --disable-progressbar but with the new --progress flag I have tried running with --progress disabled, --progress verbose_output and even no --progress flag but each one returns the same error.

The full command I'm running is: core.exe validate -s sdtmig -v 3.4 -vo -of JSON -of XLSX -o <filename> -d <path>

The error that's always returned is the following:

multiprocessing.pool.RemoteTraceback: 
"""
Traceback (most recent call last):
  File "multiprocessing\pool.py", line 125, in worker
  File "scripts\run_validation.py", line 49, in validate_single_rule
TypeError: 'NoneType' object is not subscriptable
"""

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "core.py", line 428, in <module>

I am not able to reproduce this issue. Can you try without the -vo flag?

Edit: I see this error when using the -vo flag. Removing it resolves the issue for me. The vo flag is replaced by the --progress verbose_output flag

Thanks for the prompt response Nic. Removed -vo and just went with --progress verbose_output and now it's working as expected. The README still has -vo listed so I didn't think to remove it.
