CssSyntaxError: Missed semicolon

when I add this plugin I get an error saying Missed semicolon when building my project.

It's a next.js project

this is my .babelrc

```json
{
"presets": [
[
"next/babel",
{
"styled-jsx": {
"plugins": ["styled-jsx-plugin-postcss"]
}
}
]
]
}
```
And my .postcssrc

```json
{
"plugins": {
"postcss-preset-env": {
"browsers": ["last 2 versions", "ie >= 10"],
"features": {
"nesting-rules": true,
"color-mod-function": {
"unresolved": "warn"
}
}
}
}
}
```

Even without loading any postcss plugins I get this error.
