CardDAV Synching Fails when changing existing entry (403, Cannot change the UID in an existing resource)

urbZZ

Hi,

i am running DAVDroid 1.3.6 on an Galaxy S7 Android 6.0.1.
I installed the CardDAV-Package on my Synology DS215j (DSM 6.0.2-8451 Update 7).
I exported my Contacts on my MacPro from the Contacts App in one big vCard-File and imported this file into the Synology.
Then I synched with DAVDroid and everything looks great. All Contacts are there, I can even add new ones and they are synchronized fine.
When I try to change an existing entry, everything stops working. DAVDroid throws the following Messages (excerpt):

“403, Cannot change the UID in an existing resource” seem to be the interesting bits here. Changing an existing UID is not allowed by the protocol, which is ok, but why does he even try to do that? To get things working again, I have to delete the account in DAVDroid and set it up again. Reverting the change in the adressbook, does not help here …

Any help anyone?

Thanks,

DAVdroid does not change the UID (intentionally). Please provide verbose logs of the upload process.

Do you know which UID would be expected? Can you maybe look up the contact in the .vcf that you have imported into the CardDAV server?

rfc2822

I can’t reproduce the problem with those steps:

initialize a new address book on Synology CardDAV server 6.0.4-0080
add a contact in the Synology CardDAV Web Interface
sync with DAVdroid
change the contact on the Android device
sync with DAVdroid again

In this case, everything works as expected. Maybe the problems are related to the imported contacts. Especially the X-ABUID fields look strange for me, maybe you should remove them before importing.

In any case, I can’t see a DAVdroid problem here.
