Infinite extent for field "field": [Infinity, -Infinity]

Hi all! I decided to use the suggestion on this link that suggest to create panel of vega with altair. Everything works fine except for the warning. I've tried to remove warnings on setting advance but I dindn't mange to solve. In order to save the chart I use the routines on this link. Every help will be appreciate. The problem as suggest in previous topics open is on data, (because the warning is refer to @timestamp and another date field.
I would like to hide the warning in order to work without it, maybe is it possible inserting a script on the routines on 2 links in order to add the script in this. link

chart_json['config']['kibana']={'hideWarnings': true}
