Note: The request_sync service requires that the initial sync from Google includes the agent_user_id. If not, the service will log an error that reads something like “Request contains an invalid argument”. If this happens, then unlink the account from Home Control and relink.
+Note: The request_sync service may fail with a 404 if the project_id of the Homegraph API differs from the project_id of the Actions SDK found in the preferences of your project on developer console. Resolve this by: + 1. Removing your project on the developer console. + 2. Add a new project in the cloud console. Here you get a new project_id. + 3. Enable Homegraph API to the new project. + 4. Generete a new API key. + 5. Again create a new project in the developer console. Described above. But at the step ‘Build under the Actions SDK box’ choose your newly created project. By this they share the same project_id.
