Hello, what actions were you performing in Discover that lead up to this error? Are there any failed Network requests?

Hi @jen-huang

When i search with `Last 7 days` duration in discover tab, i got this error.  
Then i search again with `Last 7 days` duration , it doesn't show again.  
I notice it's not always shown but sometimes I got this error.

I use kibana v5.5.2. I use kibana since last year, I didn't see this kind of error. But now I face this.

These days I added one scripted field (fyi)

> if (doc.containsKey('api\_timestamp')) { return (doc['@timestamp'].date.millis - doc['api\_timestamp'].date.millis)} else { return null }

Elapsed Filter added in logstash as well (fyi)

May I know what's the root cause.
