REV MUST NOT appear more than once in a VCARD component

---

No, its not working. I’ve commented already in the github issue.
Thank you for your work!

@DeepDiver Thanks, that should fix the problem.

@dervomsee

1. Please make sure that your server doesn’t serve any VCard with the questionable REV time format.
2. After that, synchronize all contacts again. You can delete the DAVdroid account and add it again (or de-select the address book, synchronize, select it again, synchronize).

Hello, I have also this issue. It begins with updating some contacts with profile pictures. The Pictures have the jpg file type.
This is the error message at the nextcloud backend:

Sabre\DAV\Exception\UnsupportedMediaType: HTTP/1.1 415 Validation error in vCard: REV MUST NOT appear more than once in a VCARD component.

I have also reference this issue here: Github contacts issue media type

@Lars This is not related to profile pictures.

1. Please make sure that your server doesn’t serve any VCard with the questionable REV time format (i.e. apply the OwnCloud Contacts fix and then correct invalid VCards).
2. After that, synchronize all contacts again. You can delete the DAVdroid account and add it again (or de-select the address book, synchronize, select it again, synchronize).

I think I found the issue myself. I added an gif

Hello,

I have the same issue. Since i have upgrade nextcloud server to 11.0 all modifications made on the phone failed on sync.
Davdroid seems to add second REV value.
Is this bug will be corrected to next release ?
I can make tests if necessary.

Best regards,

The same happened to me. I updated NextCloud from 10 to 11 (latest contacts app 1.5.2). Syncing worked fine for half an day and then suddenly I get this error while syncing contacts. It looks like Davdroid is sending invalid data to the server. Why does this happen and how can I correct this problem?

Thank you!

Why does this happen

Please read this thread.

and how can I correct this problem?

1. Please upgrade to a version of Nextcloud Contacts where the problem has been fixed.
2. Make sure that your server doesn’t serve any VCard with the questionable REV time format.
3. Synchronize all contacts again. You can delete the DAVdroid account and add it again (or de-select the address book, synchronize, select it again, synchronize).

Thank you for your answer but i confused to say that Nextcloud patch don’t solve issue.
Here are the tests performed :

1. Create contact on nextcloud
2. Sync phone with davdroid

You’re right, it’s not fixed. Starting from the beginning.

Hey people,

thanks for reporting this problem again. As @rfc2822 already wrote, this problem is not yet fixed completely. Since DAVdroid is depending on ez-vcard for contact parsing this needs to be improved inside this lib. The good thing - the developer of ez-vcard is already working on it and we will incorporate the latest version into DAVdroid soon.

In the meantime we recommend that you use any Nextcloud contacts app version except version 1.5.2. After we’ve released DAVdroid 1.3.5.1 you can again use the latest Nextcloud contacts app.

Thank you very much for your work

Should have been fixed in vcard4android/28140042 with ez-vcard 0.10.1 (thanks Mike) and thus work again in the next DAVdroid version.

DAVdroid 1.3.6 now understands timestamp values with milliseconds (and some other formats). If you have this problem (415 Unsupported Media Type with REV MUST NOT appear more than once in a VCARD component

1. update to DAVdroid 1.3.6
2. force re-download of all contacts by using one of these methods:
   • delete all DAVdroid accounts used for contacts and add them again, or
   • uninstall DAVdroid before installing DAVdroid 1.3.6 and install DAVdroid 1.3.6 / set it up again.

Hello, thanks for your great work.

Unfortunately, the problems occurs with version 1.5.0.2-ose, too.
Steps to reproduce:

• installed 1.5.0.2 freshly
• connect to nextcloud (woelkli.com in my case)
• add number to existing contact
  Please see the attached debug file and let me know how I can help resolving this issue.

Many thanks,
Christoph Hagemann0_1491656613794_DAVdroid 1.5.0.2-ose debug info

@chr There’s an invalid REV value in the VCard sent by Nextcloud, which is then stored by DAVdroid as “unknown property” (because it’s not parseable by ez-vcard):

unknownProperties=BEGIN:VCARD
VERSION:4.0
PRODID:ez-vcard 0.10.2
X-EVOLUTION-FILE-AS:Hansen\, Olaf
REV;VALUE=timestamp:2014-10-07T09:50:31Z(0)
END:VCARD
)

DAVdroid will take this unknown property and send it along with its own REV value, so that in result, there are two REV properties, which is not allowed and not accepted by the server.

Removing the invalid REV values from your Nextcloud contacts should fix that. It’s probably enough to edit the affected contacts in the Nextcloud GUI.

@rfc2822 Thanks a lot for your quick reply! You were right: Having edited the affected entry in the nextcloud GUI, subsequent edits one the mobile phone synced without a problem.

Thanks again! Christoph
