XF 2.0 Importing remote CSS file

[Brettflan]

I'm trying to import a remote CSS file within the extra.less template. Specifically, a Google font library:

@import url('https://fonts.googleapis.com/css?family=Overpass:300,400,700&subset=latin-ext');

With that added to the top of extra.less, I get a couple of server errors with every page load. The full error:

InvalidArgumentException: Template https://fonts.googleapis.com/css error: Template name '//fonts.googleapis.com/css' contains invalid characters src/XF/Template/Templater.php:551

Is there some other method I should be using to import remote CSS files within one of the ".less" templates?

Hmm, scratch that, I guess. I was getting that error in XF 2.0.2. I then upgraded to XF 2.0.4, in hopes that that would fix it. I was still getting the error, so I posted this thread for help.

However, after having fiddled around a bit more with some other templates, I found that the error has gone away. It is no longer triggering. Strange. Might be due to caching or something similar, but I assume it was indeed fixed by the upgrade from 2.0.2 to 2.0.4.

You shouldn't add that to extra.less because import statements must be at beginning of css, but extra.less is added at the end. Add it to helper_js_global after

<xf:macro name="head" arg-app="!">

Thanks for the tip.
