Edited appointments add unconfirmed "organizer" attendee

[hfball]

Describe the problem and steps to reproduce it:

Create an appointment and edit it, or edit an already existing appointment created in another app.

What happened?

Appointment is marked as tentative upon save and there is no way to change it back to confirmed in the T-bird interface. I have to go to Google Calendar on the web and answer "yes" to the "attending?" prompt to get it back to a confirmed appointment. Simply changing the status from "tentative" to "confirmed" in the Thunderbird event editing dialog and saving does not take.

What did you expect to happen?

I expected the event to remain confirmed. I expect that should it not remain tentative when changing from "tentative" to "confirmed" in the "options" menu of the "Edit event" dialog.

Anything else we should know?

Ideally, I would like a working prompt for "attending?" in Thunderbird for the event that I can reply "yes" to, but understand that this may be difficult to integrate. But definitely I want the appointment to keep its status upon editing.

Can you enable debugging and provide logs on saving the event in Thunderbird? To enable logging, see the main README.

After editing, there is an "awaiting" attendee. It's me. I have to click "Yes" that I am going before the event returns to confirmed status. This means I have to open up Google Calendar on the web to fix the problem.

Unfortunately, it doesn't appear to have logged anything other than a timezone mismatch.

On editing in Lightning, it appears in Thunderbird as "confirmed." The problem is Google Calendar doesn't agree. It thinks there is a missing attendee who hasn't responded. It also shows up on my phone as tentative.

I'm going to need a few more logs, can you follow the steps from the readme?

For debugging, please enable calendar.debug.log and calendar.debug.log.verbose in the advanced config editor (Options > Advanced > General > Config Editor) and check the logs in the error console (Tools > Error Console) for what is happening when your error occurs.

I will provide the information this weekend hopefully.

This is the log of me changing the time on the test event from 8am to 9am CST:

I don't know why the time zone errors are there. I am indeed UTC -6.

What either Lightning or Provider appears to be doing is adding me as a recipient, and then marking me as a non-reply, so I have to go into Google Calendar to answer "yes" to attending. Google and my phone consider this "unconfirmed" until I do so, but Thunderbird's calendar continues to report it as confirmed. There's a disconnect between Lightning and Google services, which include my Google calendar on the desktop and on my phone. I noticed this because edited appointments on my phone were showing as tentative.

As you can see, there is an open circle here indicating "unconfirmed."

And if I click on it, I get this:

Here's a video capture of the workaround:

You can see, at the start, that the event is listed as confirmed in Thunderbird, even though I, the organizer, am an unconfirmed attendee.

After you do what I did in the video, the event is fixed and back to confirmed on Google, because I am removed as an unconfirmed attendee. The reason the video method works is because it removes all attendees. Thunderbird initially creates the entry without an organizer. When provider pulls the event on edit, however, I become an attendee and organizer on Google Calendar. So if I open up the editing box to actually change something, and then "save and send" the event without changing a thing, that triggers the issue.

In fact, just bringing up the attendees screen and changing that blank attendee under the organizer to a non-required participant works. The problem appears to be this blank required attendee under the organizer. There is no way to delete it via the interface. Doing this is more complicated, but preserves me as the "organizer" in Thunderbird. It removes me as the organizer on Google calendar though!

Just the action of opening and saving in the edit box yields this on Google Calendar:

It's "awaiting" my confirmation, even though I am the organizer. I can't tell you if this is Lightning or Google Provider that is causing this, because there is no way to repeat the behavior without a Google calendar present. It definitely has to do with the interaction of what Lightning creates and what Provider sends to Google.

I'm pretty sure you can iron out the root cause with this info, but if you need any further logs, screenshots, or video capture lmk.

Removing personal information just got exhausting, so don't dox me, eh? 😉
