EXCEPTION of type 'KeyError'

[Houston256]

Hello, everytime i run katana i gen an error
EXCEPTION of type 'KeyError' occurred with message: ''solutions'' (verbose version below)
Thought it was a fault with the installation because I had messed around with it quite a bit so i reinstalled my OS and installed it exactly according to the instructions and still get the same error. Any ideas why this is happening?

katana - running - 1576 units queued 
➜ Traceback (most recent call last):
  File "(/home/.../katana/env/lib/python3.8/site-packages/katana-2.0-py3.8.egg/katana/manager.py", line 687, in _thread
    work.unit.evaluate(case)
  File "/home/.../katana/env/lib/python3.8/site-packages/katana-2.0-py3.8.egg/katana/units/crypto/quipqiup.py", line 108, in evaluate
    for sol in j["solutions"]:
KeyError: 'solutions'
EXCEPTION of type 'KeyError' occurred with message: ''solutions''

Kind regards
