Error installing my custom component "Config flow could not be loaded"

I am new to HA development. I found an integration that needed updating but repo owners have been unresponsive for weeks. Decided to fork and try the work my self.

Ended up forking a blueprint from ludeeus/integration_blueprint and adding component info to it. Now i can’t get it to install the integration and the error message make little to no sense to me. any help would be greatly appreciated.

Repo: GitHub - tekHudson/hass-fpl-component: Fpl Integration for Home Assistant

Error on install: Config flow could not be loaded: {"message":"Invalid handler specified"}

And i don’t see anything in the logs, how could this be???
