            if(/(unexpected)/.matcher(doc['message.keyword'].value).find()){
                return "Unexpected Error";
            }
            else if(/(memory)/.matcher(doc['message.keyword'].value).find()){
                return "Memory Error";
            }
            else if(/(memories)/.matcher(doc['message.keyword'].value).find()){
                return "Memory Error";
            }
            else if(/(equipment)/.matcher(doc['message.keyword'].value).find()){
                return "Equipment Error";
            }
            else if(/(equipments)/.matcher(doc['message.keyword'].value).find()){
                return "Equipment Error";
            }
            else if(/(parse default_repo)/.matcher(doc['message.keyword'].value).find()){
                return " Parse default_repo Failed";
            }
            else if(/(agent failed)/.matcher(doc['message.keyword'].value).find()){
                return "Agent Failed";
            }
            else if(/(process terminated)/.matcher(doc['message.keyword'].value).find()){
                return "Process Terminated with Error";
            }
            else if(/(timeout while waiting for task)/.matcher(doc['message.keyword'].value).find()){

                return "Status Update of Task not in Roster";
            }
            else if(/(end task)/.matcher(doc['message.keyword'].value).find()){
                return "End Task Error";
            }
            else if(/(environment)/.matcher(doc['message.keyword'].value).find()){
                return "Environment Error";
            }
            else if(/(error receiving event)/.matcher(doc['message.keyword'].value).find()){
                return "Receiving Event Error ";
            }
            else if(/(descriptor constraints)/.matcher(doc['message.keyword'].value).find()){

Hi and welcome to our community!

Seems the error message provided by Kibana isn't very useful, could you take a look at a single failing request in the [Browsers dev tools](https://developer.mozilla.org/en-US/docs/Learn/Common_questions/What_are_browser_developer_tools), maybe paste the the result of a failing request here, or a screenshot? there should be more info provided why this is failing.

Here's a example for debugging in chrome:

Thx & best,  
Matthias
