Can you include the tx or log data and topics?

[mhw0]

Here is the event log:

  EventLog {

That event was successfully parsed though; it has an .args property.

[mhw0]

Yes, but when you do contract.interface.decodeEventLog("TestEvent", txn.data, log.topics), it throws that exception. Maybe it's already parsed, that's why?

[mhw0]

Just didn't want to do (receipt!.logs[0] as any)["args"][0]. It looks ugly.
