The problem described in the parent task was found to happen on a few other schemas:

Schema:CentralNoticeImpression data has truncated impressionEventSampleRate
Schema:ServerTiming probably truncated data for time
Schema:Popups may have truncated data for popupDelay

Further, there are a number of fields defined as "number" that should really be "integer" on their JSON Schema specs:

centralnoticeimpression - bucket
editorjourney - http_response_code, namespace
flowreplies - pageNs
imagemetricsloadingtime - samplingFactor
servertiming - duration
wikipediazerousage - time
