* Clearing service error from invalid-key will not invoke the agent anymore

Using version 1.40, I'm trying to connect to a basic psk wifi hotspot.
If I input a wrong key to the agent request, the service will
correctly get Error == "invalid-key" (and State == "idle"). Invoking
Service::ClearProperty("Error") will put the service in a weird state:
every subsequent Service::Connect() call will fail without ever
requesting any agent input. To leave this state, one has to call
`Service::Remove()`.
Is this expected or is this a bug?
Thanks,
Andrei

This sounds like the issue I reported here:
https://lore.kernel.org/connman/20210615120930.2970caef.john@metanate.com/
I have reverted 8ea2d67a6e8935d06f71b1ec77a2f89d72be49eb locally and
that fixes this scenario.
Regards,
John

Hello John,
Even though they share a great deal, these are not similar, because
a) I'm calling Service::ClearProperty("Error"); // there's no way to
do this from connman afaik
b) I'm getting operation aborted as an error
If I skip a) then I get subsequent agent calls. Also I'm able to
reproduce the issue on 1.36.

Thanks for the reminder. I'll look into it.

Sounds like a bug to me. I think it could be that we set the error state
but don't update the ipconfig/service state accordingly. Although you
are saying the service is in a error state.
So this here is probably not helping:
--- a/src/service.c
+++ b/src/service.c
@@ -3999,6 +3999,13 @@ static DBusMessage *clear_property(DBusConnection *conn,

If possible could you check what the service state is when we hit the

return -EINVAL;
TBH, the 'set_error' thing looks a bit strange. The commit message says
service: Signal error property changes
In order to allow clients to update the property in a manner similar to
other service properties, signal changes in the service "Error" property
key/value pair.
The value "" is used when no error is asserted because D-Bus property
changed convention has no semantics for indicating a key/value pair was
removed.
Thanks,
Daniel
