Telegram Script and also require key not provided error

Configuration
1

I have issues with telegram scripts and with configuration saying key not provided even thought there isn’t any problem with function after reboot. One of the issues is got to do with script I trying to test for my telegram bots. I keep seeing the require key error since hassio 80 but never really bothered me, I have search around I have tried all the possible work around apart from reinstall.

Current Hassio Version: 0.81.0

Invalid config for [automation]: required key not provided @ data['action']. Got None. (See /config/configuration.yaml, line 266). Please check the docs at https://home-assistant.io/components/automation/ Invalid config for [script]: [flash_lights] is an invalid option for [script]. Check: script->script->script->flash_lights. (See /config/configuration.yaml, line 268). Please check the docs at https://home-assistant.io/components/script/

I’m trying to follow the @Kallb123 Telegram chatbot tutorial, and I get this error
required key not provided @ data[‘message’]
not for the main “put the bins out or get a reminder in x minutes/hours” but for the delayed callback. Finding the tutorial as a whole doesn’t work anymore - presumably the underlying code has changed a lot since a year ago?
