Invalid keyed collection item

An item in a keyed array lacks a valid stable id, or repeats another item's ID. Validation fails because item paths and merges cannot identify it uniquely.

#Common causes

• An item has no string id, a malformed ID or a duplicate ID within the collection.

#Fixes

• Give every item a distinct ID in the accepted form, such as s_7c, and preserve existing IDs when editing their values.

• Submit the corrected collection with property.set, or correct the file and run ara check <file>.
