TagHistoryQueryParams aggregation mode now required in Ignition 8.3.4?

Something changed between Ignition 8.3.0 and 8.3.4 such that the AggregationModes passed by TagHistoryQueryParams to TagHistoryManager.queryHistory() can no longer be null (an exception is thrown now).

I don’t want any aggregation, I just want raw data, so I tried passing in an empty list. An exception is no longer thrown, but now a weird data point is returned that is in the future. It seems like maybe it’s the last value? But it has a future timestamp, roughly four hours into the future.

Anyone have any idea what this is? Is there a proper way to specify that you do not want any aggregation to be done?

The history provider in this case is Core Historian.
