DF0041: JSON-Render Spec Is Not JSON-Serializable

JSON-render view "{id}" spec is not JSON-serializable: {reason}

Message

JSON-render view "{id}" spec is not JSON-serializable: {reason}

Cause

Specs and state travel across the RPC / static boundary as strict JSON. A spec containing functions, symbols, class instances, Map/Set, or circular references cannot cross that boundary, so it is rejected at ingress.

Example

const spec: any = { root: 'a', elements: {} }
spec.self = spec // circular reference
createJsonRenderView(ctx, { id: 'x', spec }) // ✗ throws DF0041

Fix

Keep specs and state strict JSON: remove functions, symbols, class instances, Map/Set, or circular references.
