$ signal-cli --version
signal-cli 0.8.0

The message actually is sent and is received on the recipient's device. It is not however shown on the 'linked' devices (the syncMessage to them not sent?).

Running with --verbose does not seem to provide other clues.

I have tried to use the previous version (0.7.4) for comparison, but it produced a different error (I guess the fields in the config file have been changed since):

$ ./signal-cli-0.7.4/bin/signal-cli  send +XXXXXXXXXXX -m "Message"
ERROR App - Error loading state file for user +YYYYYYYYYYY: Unrecognized field "about" (class org.asamk.signal.manager.storage.profiles.SignalProfile), not marked as ignorable (5 known properties: "unidentifiedAccess", "identityKey", "name", "unrestrictedUnidentifiedAccess", "capabilities"])
 at [Source: UNKNOWN; line: -1, column: -1] (through reference chain: org.asamk.signal.manager.storage.profiles.ProfileStore["profiles"]->org.asamk.signal.manager.storage.profiles.SignalProfile["about"])

I'm at a loss what would start causing this. Everything had been working fine; I don't think I've changed any relevant components, and this does not look like an error coming from signal servers.

For completeness, the --verbose output:

Can you check if it works with the latest master.
I fixed an issue with broken session records there, which manifests itself with the same stack trace.

Altough I'm not the original reporter, but I had the same issue. I build signal-cli based on master and can confirm that messages are being send again without error.

Will report back if problem reappears.
(Last time it did not appear immediately).

Running the latest master, the issue is gone. Thanks!

Weird how it started happening without any actions on my side (that I'm aware of). The underlying problem must then be the same as in #530, although I haven't touched the master signal app on the phone.
