4.x - Importing modular scale using ratio string results in an error

[joyheron]

I'm testing out the new modular scale implementation in my project, and I've been pretty successful in migrating my code frommodularscale-sass in version 3.x to the new 4.x branch, but I currently have an issue with loading the ratio.

I've tried out both methods for importing and overriding the settings:

METHOD 1:

@use "modularscale-sass/stylesheets/modularscale" as ms with ($settings: (base: 1rem, ratio: 'minor-second'));

or

METHOD 2:

@use "modularscale-sass/stylesheets/modularscale" as ms;
$base-font-size: 1rem; // 16px
ms.$settings: (base: $base-font-size, ratio: 'minor-second');

This appears to me to be the desired syntax based on this documentation: https://github.com/modularscale/modularscale-sass/tree/4.x#ratios

However, when I try to compile my sass code, I get the following error:

aborting: Error: $number: "minor-second" is not a number.
   ╷
21 │   @if unit($ratio) != "" {
   │       ^^^^^^^^^^^^
   ╵

This error occured using the v4.0.0.rc2 version.

I've also tried it based on the v4.x-iteration branch, and there I get the following error when importing using METHOD 1:

aborting: Error: $base: radio-target("minor-second", 1rem) is not a number.
   ╷
94 │     @return math.pow($ratio, $v) * $base;
   │             ^^^^^^^^^^^^^^^^^^^^
   ╵

Using the number value of the ratio (1.067) works, but I would prefer to specify the name of the ratio if possible.

Note: on the 4.x-iteration branch the import using METHOD 2 doesn't appear to compile at all. I get the following error:

aborting: Error: Undefined variable.
  ╷
2 │   $settings: (),
  │   ^^^^^^^^^
  ╵
