After upgrade from 6.4 to 6.5 we get the following warning when loading a dashboard consisting of some pie and heatmap visualisations

malformed filter agg params, missing "query" on input
Then when clicking in the pie visualization to further apply filters nothing happens and we get this error on the console.
```

```
Clicking the heatmap visualization this error pops out on the console.
```

When downgrading back to 6.4 everything works great again.
Is it a bug in Kibana 6.5 or something we've done very wrong?

Hello,
It looks similar to this bug logged: [https://github.com/elastic/kibana/issues/23532](https://github.com/elastic/kibana/issues/23532)
@timroes can they safely keep using 6.5 in spite of this?
Thanks,
Bhavya

I think that's a different issue. @flalar Please create an issue for that on GitHub. Please also narrow down which of the visualizations on the dashboard is throwing that and attach the saved object of that visualization.
