Struct SessionCanvasUnavailableData 

pub struct SessionCanvasUnavailableData {
    pub canvas_id: String,
    pub extension_id: String,
    pub instance_id: String,
}

Session event “session.canvas.unavailable”. Transient signal that an open canvas instance’s provider has dropped (for example the extension is reloading mid-session). The host should keep the panel mounted and surface a reconnecting affordance rather than tearing it down; a subsequent session.canvas.opened for the same instanceId clears the affordance once the provider reconnects with a fresh url. Ephemeral and never persisted, so it is never replayed on cold resume.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Fields

canvas_id: String

Provider-local canvas identifier

extension_id: String

Owning provider identifier

instance_id: String

Stable caller-supplied identifier of the canvas instance whose provider became unavailable
