[Bug]: Strict unary deprecation in Sass #17593

Closed

Description

Package

@carbon/styles

Browser

No response

Package version

1.66.0

React version

18.2.0

Description

I get this warning when building:

DEPRECATION WARNING on line 128, column 20 of ../../node_modules/@carbon/styles/scss/components/modal/_modal.scss: 
This operation is parsed as:

    -$spacing-05 - $spacing-05

but you may have intended it to mean:

    -$spacing-05 (-$spacing-05)

Add a space after - to clarify that it's meant to be a binary operation, or wrap
it in parentheses to make it a unary operation. This will be an error in future
versions of Sass.

More info and automated migrator: https://sass-lang.com/d/strict-unary
    ╷
128 │     margin-inline: -$spacing-05 -$spacing-05;

I'm using Sass 1.69.7
