CardDAV fatal error when PHOTO VALUE is binary uri

[balleyne]

For months now, my Davdroid to ownCloud contacts sync has been broken, while my IceDove SOGo connector sync has been working fine. I upgraded from ownCloud 9.1. to NextCloud 10 to NextCloud 11 to see if moving to the latest version would resolve my error. It hasn't, but it has brought clarity to the server side error message.

Steps to reproduce

1. Configure Davdroid sync per https://davdroid.bitfire.at/configuration/nextcloud/
2. Sync addressbook

Expected behaviour

Addressbook should sync.

Actual behaviour

NextCloud produces a 500 error.

This is from the nextcloud logs:

The key error being: Unsupported VALUE parameter for PHOTO property. You supplied "binary[c3][be]uri"

It appears that I have 131 contacts (between various uses on my NextCloud instances) with these binary PHOTO properties:

I believe this PHOTO;VALUE=binary uri whatever thing is causing NextCloud to throw a 500 error and it causes synchronization to fail entirely with some clients, like Davdroid.

Pffff... my bet is that some invalid client uploaded those. But now that sabre does more (and way better) sanity checks they don't get properly synced anymore...

So probabaly davdroid requests a slightly different format than the sogo connector etc.

[balleyne]

Thanks for the replies.

Yes, probably the fault of a client I was using, though it seems like that format may have been valid for vCard 3.0, but perhaps is no longer valid for vCard 4.0? Found this: https://github.com/fruux/sabre-vobject/issues/325#issuecomment-227491978

It's not a Davdroid error though. Davdroid is triggering a 500 error on the web server from NextCloud (I guess calling something that SOGo Connector for Thunderbird doesn't...). It seems like a bug to me that if there's vCard data that used to be valid until (probably) a NextCloud ( / Sabre ) upgrade, the server then starts throwing a 500 error. I think an improvement would be skipping the effected contacts and notifying the user somehow that there's a problem with the data?

Let me know if there's anything I can do to help... I hope to find a way to fix my data soon, after which it'll be harder for me to do testing.

Thanks again.

@balleyne is this still happening on newer nc versions? (nc 14 or 15)
