What probably matters to youSection of the release
What
An artifact reading or writing the data/users collection can use the document id me and it is rewritten to the caller's real user id. The id is fetched once and cached per account, with concurrent lookups sharing one request.
Details
If the artifact's published version does not declare both the database and user capabilities, the error says the artifact needs republishing rather than failing opaquely.
Evidence
resolving 'me' needs this artifact's published version to declare the db and user capabilities
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
