[script_exception] runtime error bad request

Elastic Stack Kibana
1

Hi, I am new in Kibana .So I added a scripted field in one of the index pattern. I am pretty sure the code should work fine.

if (doc['message.keyword'].value.contains('errCode')) {
return "match";
}
return "No match";

When I previewed the results, it works fine. However, when I tried to view it in Discover, it said "error loading data, [script_exception] runtime error".

Error: Bad Request

Hi bob

The error message you posted does not give us enough info to troubleshoot. Are you able to get any other error messages from your kibana or elasticsearch logs?
