aws-amicleaner Invalid length for parameter LaunchConfigurationNames[0], value: 0, valid range: 1-inf

I've been using this tool for the past week without an issue, but yesterday I started getting an error message when trying to perform a clean:

Invalid length for parameter LaunchConfigurationNames[0], value: 0, valid range: 1-inf

This is the command I'm running

amicleaner --mapping-key name --mapping-values my-ami-name --keep-previous 3

@Mattnmoore I tried forking this repo, and implementing the changes in https://github.com/bonclay7/aws-amicleaner/pull/87, but it didn't work. Do you have a working fork?
