caldav sync with Runbox stopped to work : "Integrity constraint violation: 1052 Column 'displayname' in field list is ambiguous"

[Saroumane]

Hello,

a few days ago DAVx suddenly stopped to sync with my caldav remote Runbox calendar.
I upgraded to latest DAVx 2.4 but the error is still there.
I get a HTTP 500 Internal Server Error, the Interesting part seems to be here :

<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
  <s:sabredav-version>3.2.2</s:sabredav-version>
  <s:exception>PDOException</s:exception>
  <s:message>SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'displayname' in field list is ambiguous</s:message>
</d:error>

Has something changed recently on DAVx side regarding this ?
Or if the problem is on server side what should I say to them ?

Thanks for your help !

Hello,

This sounds like a server database problem (problem with the displayname field). Do you know what server software is used?

Is there any indication that this could be a client problem?

Thanks for the quick reply.

@Saroumane said in caldav sync with Runbox stopped to work : "Integrity constraint violation: 1052 Column 'displayname' in field list is ambiguous":

<s:sabredav-version>3.2.2</s:sabredav-version>

I guess Sabredav 3.2.2 could be the server software.
It sounds like a server problem indeed, so i think I’ll open a ticket on Runbox side, with the debug log.

@Saroumane Thanks. Would be kind if you could tell us when you find out what it was!

@rfc2822 They know the problem and are working on a fix.

After that, maybe you can add Runbox to the list of Tested servers

@Saroumane Thanks for the update!
