Hi everyone

I would need some help with this error. See below the description:

In Kibana UI the "More info" displays:

And the full request that causes the problem, ...i think is this:

I can't figure it out.

I need some more context on this. What are you trying to do that causes this error?

It just appears whenever I have any default index pattern is selected. In the Discover tab, when it loads the page, it displays the error.

The indexes are accessible from the Console and the fields are visible in the visualisations as well.

Thanks

What version of Kibana are you using? What is the config of the default index pattern? Are you using any scripted fields?

</div>

Kibana 6.2.2  
No scripted fields  
The default index pattern is an index i have created but with .kibana i get the same behaviour and as for the id I have let kibana get an id for me but also tried to define an id myself. In all cases the same error.

I think the issue may be with the data and mapping in your index. I think that a field that is mapped as a number type in Elasticsearch has some values that are just "" instead of a number. See this post for possible resolutions: [Number format Exception For string type](https://discuss.elastic.co/t/number-format-exception-for-string-type/59175)

I was looking at that but then I have tried to setup an index without number mappings and I am running into the same issue with the default .kibana index pattern.

Maybe your .kibana index is corrupted. You could try deleting it, as it gets recreated when Kibana starts up and it is not present.
