Hi, since yesterday I have the following error in Kibana:

`TypeError: Cannot read property 'valueOf' of undefined at Timefilter.get (http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/commons.bundle.js?v=14566:47:1338) at http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/kibana.bundle.js?v=14566:28:8139 at http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/kibana.bundle.js?v=14566:27:30889 at SearchSourceFactory.SearchSource._mergeProp (http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/kibana.bundle.js?v=14566:27:30969) at ittr (http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/kibana.bundle.js?v=14566:27:4132) at http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/commons.bundle.js?v=14566:1:19774 at http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/commons.bundle.js?v=14566:1:30010 at baseForOwn (http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/commons.bundle.js?v=14566:1:16915) at http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/commons.bundle.js?v=14566:1:29575 at baseMap (http://elastic01.mvlab.cumulusnetworks.com:5601/bundles/commons.bundle.js?v=14566:1:19707)`

I am still able to query documents from the search API though so I don't really understand the error..

Thanks,  
Quentin

Found what was causing this issue..

It was a simple typo mistake in timepicker:timeDefaults in Kibana's Advanced Settings and I forgot to reload the UI after making some changes.
