Zotero Integration Error

Fini1984

Hi community
I'm using the Zotero add-in for LibreOffice 5.1.4.2 and Zotero 4.0.29.10 as stand-alone version.
My operation system is Ubuntu 16.04 and I use the JRE Version 8 Update 111. After clicking on the insert citation button or the Refresh button the following error occurs:

An error occurred communicating with Zotero:
com.sun.star.lang.IllegalArgumentException:

I've already restarted my computer but without success.
Would be thankful for any kind of help.
Thanks!

I just updated Libre Office to version 5.2.3.2 but the error occurs again

It seems to be a problem in the specific document - when inserting a citation into another document, the error does not occur. Is it possible to further narrow down the cause?

Use these instructions: https://www.zotero.org/support/word_processor_plugin_troubleshooting#debugging_broken_documents

Thank you for the link.
The cause of the error was a set of citation in a table that were turned by 90°.
After removing the citations, the error did not occur. Then, I added the citations anew an the error ocurred again.
The funny thing is: There is a second table in the document with the same citations, also turned by 90° and they are working...

Hard to say, but citations in LibreOffice tables, especially multiple citations in a single table, aren't very robust.
