help me inject var to stylus with additionalData

[badoubadou]

Hello every one,
I'm trying to add some variables to be used with in stylus.
Here is my build in nuxt config.

build: {
    loaders: {
     stylus: {
       additionalData: `$myred: #000FFF`,
     },
   },

When I use it it break my build. It add correctly the var, but just after it, I get trough an error :
expected "indent", got "import".

But if I had the same var at the top the main stylus file it works fine.

Is it not the right way to do it ?

Thanks !
