I have upgraded Kibana from 2.3 to 5.3 and when I created the indexes I started to see this error.

Saved "field" parameter is now invalid. Please select a new field.

```
Discover: "field" is a required parameter
TypeError: "field" is a required parameter`

Usually what this means is that you have a field in your mapping which has no values associated with it. Is this the case? If so, can you remove that field from your mapping and try again?
