Error log: Unknown receipt type in envelope

[moppman]

I noticed this type of error in the scli error log:

ERROR:root:on_receive_receipt: unknown receipt type in envelope {'source': '+xxx', 'sourceNumber': '+xxx', 'sourceUuid': 'xxx', 'sourceName': 'xxx', 'sourceDevice': 1, 'timestamp': xxx, 'receiptMessage': {'when': xxx, 'isDelivery': False, 'isRead': False, 'isViewed': True, 'timestamps': [xxx]}, '_received_timestamp': xxx}

Looking at the relevant scli code, there are two types of recognized receipts: isDelivery and isRead, probably corresponding to the two well-known checkmarks.

So I'm curious: what type of receipt is signal-cli receiving that is neither isDelivery nor isRead?

Good question, I'd like to know as well! I've asked upstream: AsamK/signal-cli#948

Now the isViewed receipts are ignored by scli rather than log an error (66e1dc3).
