Error when processing map

[mikeebee]

Hi,

I copied code directly from an example and I'm getting an error.

This is the code I'm trying to get working - http://codepen.io/erskine/pen/xEqFC

When I process this through LibSass, I get this error

argument `$map` of `map-get($map, $key)` must be a map

Backtrace:
    sass/[filename].scss:55, in function `map-get`
    sass/[filename].scss:55, in function `_fontset-feature`
    sass/[filename].scss:60, in function `calc-font-size`
    sass/[filename].scss:73, in mixin `font-scale`
    sass/[filename].scss:86
Line 55  Column 22  sass/[filename].scss

The line with the error is from the _fontset-feature function...

$result: map-get(map-get($family, $set), $feature);

Any ideas?
Thanks!

A wild guess would be that map-get($family, $set) returns no result, so null, which is not a map for map-get(null, $feature).

Anyway, I just tried this code on SassMeister and there is no bug whatsoever. I'm pretty sure it's due to a configuration issue with a non-existant map / key. I think you can close.

If I may ask, why would you even think there is a bug with LibSass rather than the code you copy/pasted?

Couple of reasons:

1. I had similar errors when trying something like this before, and it was a bug in LibSass.
2. Since it was functioning on Codepen, using Sass, I assumed it would work if copied into my environment.

Sound ok?

I think the first issue is related to map keys being colors instead of strings, so it might be a different problem.

Regarding environment, CodePen is running on Ruby Sass, but you try LibSass on SassMeister. I did with your code and had no bug. :)

Ah, must be an issue with my setup as I copied the code directly.

Thanks for your input!
