Fastlane match not found in available list of options

I'm working in a forked React Native app and it has fastlane already setup with Matchfile, Fastfile& Appfile but upon editing the Matchfile to match my repo and username, and ran fastlane match appstore, it doesn't work and gives me Matchfile data found and an error:

[!] Could not find option 'match' in the list of available options: 'OPTIONS HERE'

Ironically, this command runs just fine: fastlane match --help.

I would go and file for an issue on Github but wanted to try my luck here first.
