This contextual rule applies no lookup

Hello,
I am trying to ligaturize the Oxygen mono font. I have installed fontforge and python-fontforge but when I run the script i get the error This contextual rule applies no lookups.
Below is a post of my terminal display:
fontforge -lang py -script ligaturize.py fonts/OxygenMono-Regular.ttf --output-dir fonts/ --output-name='Oxygen Mono Code' --ligature-font-file fonts/fira/distr/otf/FiraCode-Regular.otf

What does this error mean and how do I fix it?
This warning is normal; you'll note that the built in build script filters out those messages so that actual problems can be seen in the output. It should not prevent it from generating the output font.
Unfortunately I don't know enough about font lookup tables to understand why it does this or how to stop it, but it doesn't seem to affect the validity of the generated fonts.
