Background
During end-to-end testing of the Java client, 2 properties did not pass validation:
- wikidata_id
- registration_dt
See T327083#8635819
This ticket depends on T330459
Description
Fix the types of wikidata_id and registration_dt to pass EventLogging validation when those context values are added to a stream config.
Acceptance criteria
- Java client passes a new property called wikidata_qid that is of type string instead of integer
- Java client registration_dt is a string of date-time format that passes EventLogging validation
