How to add system intents (e.g. actions.intent.MEDIA_STATUS_FINISHED) to the Google Assistant Action Builder

Question

How can I add a system intent to the scene in the Action Builder?

E.g. I want to add one of the media intents: actions.intent.MEDIA_STATUS_STOPPED, actions.intent.MEDIA_STATUS_PAUSED,...

When you try to add one of these to the scene, you will get the error:

Name can only contain letters, numbers, and underscores. The name also must start with a letter.

If you try to add it without the "actions.intent." part, e.g. MEDIA_STATUS_STOPPED it will be treated as a user's custom intent. And because of it, it won't handle any callback for the Media object state changes.

The documentation is silent about it.

It sounds like you're trying to add these Intents under the "User intent handling" section of the Scene. But these aren't user intents - these are system intents that have been pre-defined. So instead you add them in the "Error and status handling" section.

When you do, the pane on the right will let you select a System Intent to setup processing for.

You can then select the System Intent from the drop-down menu, including MEDIA_STATUS_STOPPED, etc.

Once you have, you can then setup how you want to handle that System Intent (calling a webhook, sending prompts, and/or transitioning to another scene).

You can then repeat this, as necessary, for any other media status system intents.
