[Spine] No model source provided

Error message

[Spine] No model source provided

What it means

The Spine Model component's load routine requires the modelSrc prop (skeleton + atlas source). When it is empty, the component disposes any previous Spine instance, clears modelLoading, sets componentState to 'mounted' and returns — a controlled no-op, not a crash.

Solutions

1. Provide a valid modelSrc pointing at the Spine skeleton/atlas source
2. Render conditionally: <Model v-if="modelSrc" :model-src="modelSrc" /> and show a placeholder state otherwise

Example fix

// before
<Model />

// after
<Model v-if="modelSrc" :model-src="modelSrc" />

// Before rendering the Spine model
// template: <Model v-if="modelSrc" :model-src="modelSrc" />

function isModelSource(value: unknown): value is string {
  return typeof value === 'string' && value.trim().length > 0
}

When it happens

Trigger: Rendering the Spine <Model /> without modelSrc, or with modelSrc bound to a value that is still undefined while settings/model stores load.

Common situations: No Spine model selected during onboarding; passing only identifiers and expecting the component to fetch the source; conditional sources that start as undefined.
