"Transaction failed on small parcel" on LineageOS when synching calendar

[TheDromundKaas]

Good evening,

I've recently upgraded from my old Fairphone3 with /e/ to a Oneplus 9 Pro with LineageOS. I've been using Davx5 for quite a few years with my old phone, and I wanted to set up the same synch I had on my old phone.

My E-Mail-Provider (Posteo) supports synchs. So I set up everything, and most works, but the calendar synch intermittently does not - see the attached log reports. As far as I can see, it happens only on calendar synch, as when I manually start one from the Davx5 UI the error pops up.

The error has not always happened, as I had days where my calendar is synched perfectly, and the calendar widget shows my appointments.

I have found the error message in other software contexts, however, I am not sure what is a course of action I can take to work around that.

Hi,

thanks for the report. I've seen this a few times reported already - a certain Lineage version for Android 13 was broken. It can only be fixed if you're updating/downgrading the LineageOS version of your device. This version seems to have had an error with the Calendar and Contacts storages not allowing a certain process size needed for the transaction of the data.

Hope it helps!

That was a very good hint. I've updated to a LineageOS version from yesterday, and I cannot reproduce the issue. Thank you very much.

Sorry to necrobump this. I'm on GrapeheOS in order to have recent OS security updates. Graphene just upgraded to Android 14. Since a couple of days (so, before I got A14!), I get these messages, too:

Quite annoying since they pop up frequently and for multiple inscances configured. What shoud I do? (Downgrading is not an option!)

I may provide a debug.zip if told where to since it contains sensitive data.

You can only try to reset the apps "Kontaktespeicher" and "Kalenderspeicher" to work defaults (these are preinstalled system apps on every Android device), and then force the sync of DAVx5 again. It will first delete all local contents (= all contacts and calendars) from your Android device ( !!! also stuff not managed by DAVx5 !!!) and then sync it again. If it is still broken you can try to reset the whole device to work defaults. If it is still broken after that you can't use DAVx⁵ with GrapheneOS (at least not with the builds you have for your device).

I "solved" it by pinning the DAVx5 notification. Seems to be some timeout or ressource value change in GrepheneOS defaults.
