ClassicLogs API -> sourceid for auras not supported


I try to get the results that are for example displayed here:

My API call:

Issue: Buffs that origin from a different player (e.g. Power Infusion) are not listed.

Calling returns “{ “status”: 400, “error”: “Only ‘source’ and ‘target’ are supported for auras views.” }”

Is this a bug or am I missing how I could retrieve the information I seek?
