Summary
When deleting a record it's possible to set
data
to be nil. In that case the row would be removed from therecords
table, but there would be an entry in therecord_changes
table withnil
data. The call to stream changes would then attempt to convert this row into a record and fail with an error. This PR updates the code to tolerate nil data.Any consuming code would also need to tolerate nil data accordingly. Whether that's the case or not for all known usages is unclear.
