Biome grit plugin using range fails to compile

[kolben]

I am trying to write a simple Grit plugin that makes sure all files contain a copyright header. The following Grit QL works fine in the Grit Playground but fails to compile in Biome.

range(start_line=2,end_line=2) as $line1 where {
    ! $line1 <: "// Copyright (c)"
}

I have tried other sample plugins so I guess it is the range pattern causing issues?
Is this expected? Can someone nudge me in the right direction on how to solve this differently?

(Tried on Linux/Bun and Windows/Pnpm)

At a quick glance, I don't think biome fully supports that range function. Feel free to open an issue about it.
