dashArray Syntax Support

Hello and have a wonderful last day of the week:)

Problem/Motivation

I'm creating a view and trying to show some polyline geometries as dashArrays. In order to do that, I've modified the Path Geometries Options as below:

{"color":"{{ field_color }}","opacity":"1.0","stroke":true,"weight":"{{ field_weight }}","dashArray":"{{ field_dash_array }}","fill":"false","fillColor":"*","fillOpacity":"0","radius":"6"}

But it doesn't work. I've tried typing different variations and then, I'm stuck.

What could be the working syntax for that?

Best,
Orkut
