I am attempting to use the tutorial located here: https://github.com/actions-on-google/dialogflow-helper-intents-nodejs
I have created an entirely new agent to make sure none of my existing intent settings are causing this. I import the file helper-intents-examples.zip and modify NOTHING in ANY of the intents. I go to Integrations->Integration Settings, add all of the intents, and hit test, and I get the following error for every single second turn intent:
Request contains an invalid argument. Query pattern is missing for custom intent 'X'
I have found no tutorial that doesn't result in this error for the confirmation/rejection/permission response intents. This error is incredibly generic and unhelpful in solving this issue.
