Property of [`Problem`](Problem.md) · stable · since 2.0.0

```ts
readonly path?: string;
```

JSON path or member path the problem is about. For an asset failure of a collection item (a
`model` item's GLB, a `mesh` item's texture, the `problem` of a [`Collection.load`](Collection.load.md)'s
HoloAssetError) it is the item's [`SessionState`](SessionState.md) address, `/look/collections/{name}/items/{key}`
(`~1` escapes a `/`, spec section 6.9, ID8), and [`node`](Problem.node.md) is unset. For one of a
collection's stage layer ([`stage.set`](Stage.set.md), [`CollectionSpec.stage`](CollectionSpec.stage.md), an [`apply`](Writer.apply.md) that lists the collection) it is
the layer's address, `/look/collections/{name}/stage`, and [`node`](Problem.node.md) is unset.

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `path` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | pass: 20 apps (fleet cross-check: app-04c2774145, app-37356bf09f, app-4762caacdc, app-4f16d2f6da, app-4fd23bc869, app-822bb9d6aa, app-8675b3225c, app-b362a81c85 and 12 more) |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
