The autoModelId property within the GoogleCloudDiscoveryengineV1WidgetConfigUiSettingsModelConfigInfo schema has been marked as Output only. This is a breaking change: if your integration was previously setting this field, it will now fail. This field is intended to provide the model_id to use when an end-user selects an 'Auto' option in the UI, and is now server-managed.
On the positive side, the GoogleCloudDiscoveryengineV1FeedbackConversationInfo schema gains a new optional taskName property. This allows developers to associate conversation feedback with the full resource name of a Sobi long-running agent task, providing better traceability.
Finally, the completeQuery methods across various completionConfig resources have had their authentication scopes reordered. While cloud-platform is still supported, cloud_search.query is now listed as the primary scope, encouraging more granular permission usage.
