Login fails with The operation couldn’t be completed. (ProseCoreFFI.ClientError error 0.)

[neilalexander]

The username and password are fine and the log reports a successful login (as does another logged in client) but this error appears instead.

Hey @neilalexander. Thanks for trying Prose. I'm finishing up another task ATM. I'll look into this issue afterwards and let you know.

[neilalexander]

Please do let me know if I can provide any more information or test further!

[RemiBardon]

Thank @neilalexander for trying the app!
I think your issue is the same as mine, reported in prose-im/prose-wrapper-swift#2 and #129.

You can try what @nesium proposed in #129 (comment), but I believe you already did seeing your log is more verbose than the one I had.

I didn't take the time to dig into the issue either, but I can try to reproduce if needed.

[RemiBardon]

@neilalexander The issue was fixed, can you try logging in again using the latest commit on master?

[neilalexander]

The ProseCoreFFI.ClientError is gone now, but replaced with a new error:

XMPP error: XMPPError { kind: Some(Cancel), text: Some("No module is handling this query"), status: Some(ServiceUnavailable) }

Should I be able to log in using a normal XMPP account?

Hey! Sorry for the confusion.

I'm assuming that you might be connecting against a server that doesn't support vCard4 Over XMPP (hence the error message).

We're not yet at a point where we have fallbacks in place when a server doesn't support certain protocol extensions. I guess we’ll have specific requirements for a server to work with the Prose client, especially since it needs to function in a workplace setting, but alas, we haven’t documented these yet. So this is all very early stages.
