I have recently upgraded the ELK stack from 5.4.2 to 6.0.0 and I have an issue in kibana where in the **Discover tab or Management \> Index Patterns tab I have an ajax error** saying: "Cannot read property 'message' of null". This comes from one of the bundles `/kibana/bundles/kibana.bundle.js?v=16070:231:27746` The ajax request is the following (will break on any pattern given) `HTTP 400 -- /kibana/api/index_patterns/_fields_for_wildcard?pattern=...` So far I have done; - a fresh re-install of elasticsearch/kibana/logstash, - enabled/disabled x-pack along with custom realm, - uninstall x-pack, - used tar.gz items to override the .deb package stuff (in /usr/share/kibana) for **kibana** All the other features of kibana seems to work just fine. I can use the console and `_cat/indices` just fine and all my stuff seems to be there. I have tried and upgraded kibana index from 5.4.2 to 6.0.0 without issues, that didn't seem to help so I also re-created one from scratch. Didn't help either. Basically whenever I hit the Discover tab or the Management \> Index Patterns tab I see the normal "first setup" page Configure an index pattern BUT when I try and add an index, it will fail (with the above error) and will also set kibana **defaultIndex** setting, and from there (unless I remove that default) the aforementioned tabs will simply display a blank page (not even the setup part). ---

Hi @g-vamp, would it be possible for you to provide the relevant console log output of the Kibana server for that request? ---

For sure! Here is the kibana client side error from the ajax request followed by the json console output. ``` TypeError: Cannot read property 'message' of null at https:///kibana/bundles/kibana.bundle.js?v=16070:231:27746 at processQueue (https:///kibana/bundles/commons.bundle.js?v=16070:39:9912) at https:///kibana/bundles/commons.bundle.js?v=16070:39:10805 at Scope.$digest (https:///kibana/bundles/commons.bundle.js?v=16070:39:21741) at Scope.$apply (https:///kibana/bundles/commons.bundle.js?v=16070:39:24520) at done (https:///kibana/bundles/commons.bundle.js?v=16070:38:9495) at completeRequest (https:///kibana/bundles/commons.bundle.js?v=16070:38:13952) at XMLHttpRequest.requestError (https:///kibana/bundles/commons.bundle.js?v=16070:38:14800) { "type":"response", "@timestamp":"2017-12-04T14:17:55Z", "tags":[ ], "pid":1733, "method":"get", "statusCode":400, "req":{ "url":"/api/index_patterns/_fields_for_wildcard?pattern=logstash-*&meta_fields=%5B%22_source%22", "method":"get", "headers":{ "accept":"application/json, text/plain, */*", "accept-encoding":"gzip, deflate, br", "accept-language":"en-GB;q=1,en-US;q=0.9,en;q=0.8,fr;q=0.7", "host":"", "kbn-version":"6.0.0", "referer":"https:///kibana/app/kibana", ... stripped some custom headers from our proxy ...

Interesting, it looks like there is a `%5D` missing at the end of the url. Does your proxy accidentally truncate that url? ---

Nice catch! This is exactly what was the problem! Many thanks for your help! ---
