Hi,

On a cross cluster, using kibana, I'm trying to add a runtime field in a dataview pointing to a remote index. In the preview section, a "script error" message is displayed.  
My script code: `emit('TEST');`  
Did I forget to configure something ?  
Is it possible to create a runtime field on a cross cluster ?

Thx for your help.  
Khaled

When using the runtime\_field api to create the field :

The field is created with no request error.  
Checking in kibana :
