FAQ: When I use environments in a Google Dialogflow bot, can I remove an intent?
If you choose an environment in the Call Dialogflow bot action and remove intents from the draft version of the agent, then the flow takes the failure path. This action occurs because the flow cannot reach the deleted intents. Therefore, even though the agent fulfills the intent, the flow takes the failure path.
To ensure that the Draft environment always includes the entire set of intents in the published environment, only add intents during the life cycle of an agent throughout various environments. Do not remove them. You can also export the agent configuration into a new agent and then set the intents as appropriate. Then, update the Architect flow to reference the new agent.
To perform this task, you must create a new agent. Export the current agent’s configuration into a new Google Dialogflow agent, then remove intents and slots as appropriate. Then, reference the new agent from the Architect flow instead. Going forward, follow the add-only approach described previously.
