Error when trying to apply OS Zoomstack

[saberraz]

I am trying to apply styles for zoomstack: https://github.com/OrdnanceSurvey/OS-Open-Zoomstack-Stylesheets/tree/master/Vector%20Tiles/Mapbox%20GL%20Styles

to: https://s3-eu-west-1.amazonaws.com/tiles.os.uk/data/vector/open-zoomstack/{z}/{x}/{y}.pbf

And I get this error:

skipping non-float opacity ['interpolate', ['linear'], ['zoom'], 5, 0.6, 9, 0.5, 12, 0.1]
