Collection constraint

What it means

The collection does not accept this asset: its type is not in allowed_type_ids, it carries none of allowed_category_ids, or the collection is published and the asset is not. errors[].path names the rule; GET the collection to see its constraints.

What to do

Read errors[].path for the rule: allowed_type_ids (add an asset of an allowed type, or widen the list with PATCH /api/v1/collections/{id}), allowed_category_ids (assign the asset one of the categories in the app), or published (the collection is published; publish the asset first, in the app).

Example

Sent as application/problem+json with status 422. detail varies with the request; branch on type.
