Hi @cr_168328

in order to produce an array of values in runtime fields you can emit multiple times a single value.  
In your case rather than populate an array of value in the loop, just emit the value.

For more details about array values support for the runtime field `emit` there's this nice reference post: [How to a emit a value for a runtime field of type geo\_point? - #5 by rcowart](https://discuss.elastic.co/t/how-to-a-emit-a-value-for-a-runtime-field-of-type-geo-point/271889/5)
