This is due to option validation that expects an array https://github.com/zigbee2mqtt/hassio-zigbee2mqtt/blob/dev/zigbee2mqtt/config.json#L124

I will have to check if options allow multiple option types in the schema.

makes sense :) I stuck with the string option for now. I actually never checked if that supports generate, or if it'll cause issues with the key changing on reboots.
