Sending message to group issue

[eugenyuk]

Hi,

For some reason I've strarted to encountered with the following problem when send a message to a group: the message was sent and I see it reached the group, but signal-cli shows the following:

$ echo 'Test message' | signal-cli-native --config /home/.local/share/signal-cli -v --scrub-log -a +123456789012 send --message-from-stdin -g ***

signal-cli could send the message to most group members:

2026-05-31T11:07:55.158Z [main] DEBUG o.a.signal.manager.helper.SendHelper - Successfully sent using sender key to 146/146 sender key targets.

The error is about one group member that has unregistered from signal, so the message couldn't be sent to just this one member:

2026-05-31T11:07:55.356Z [virtual-71] WARN LibSignal - [SignalServiceMessageSender]: [1780225673105] Hit unregistered user: ********---****-**********95
