i think this should have a null check (if this.options)

Yes, perhaps, but it seemed like options would always have a value (an object):

But I'm not sure if it's is called from other modules. I quickly checked but couldn't find anything.

Should I add the check? It's ok to me. Not sure what your practice is here (how strict).

We prefer to have null checks because it can crash a process if you forget
it. Options are usually optional, so making sure there is a reasonable
response when the options are missing is preferred.
