Internal Server Error

[judewang]

Hi, my name is Jude.

I found that using Middleman v3.3.3 with middleman-autoprefixer v2.1.0 will an issue that make browser failing to load stylesheet after refreshing the page. It sent a message said "Failed to load resource: the server responded with a status of 500 (Internal Server Error) " to browser's console window. I have tested this with middleman-autoprefixer v2.0.1 and it was OK. I think the issue will be produce only when using v2.1.0.

Thanks.

Can you paste the contents of the stylesheet before Middleman tries to process it?

[porada]

@judewang, I think I might know what’s responsible for causing this, but I’d still need your stylesheet to test it out.

@porada, I'm having a similar issue I thought I'd chime in with as my behaviour isn't described exactly. I get the same 500 error (still happening with v2.1.1), although on a subsequent refresh it works fine, i.e. if I keep refreshing the page, every second time it works. I haven't had a chance to make a sample stylesheet for you as it's quite a large application and the stylesheet is spread across many files. I thought the information may be useful to you regardless.

Cheers,
Nathan

I'm also having this issue exactly as described by @thenathanjones, @porada could you perhaps tell us your suspicions?

[porada]

Pushed the possible fix for this issue.

@pedropereira, @thenathanjones, and @judewang: could you test your stylesheets against the current master?

gem 'middleman-autoprefixer', github: 'porada/middleman-autoprefixer'

If this fixes the problem, I’m going to release the next version right away.

[pedropereira]

Awesome, that definitely did it for me. Thanks for the fix 👍

[porada]

Great. Enjoy the v2.1.2. 😀

I'm still experiencing this issue. middleman server —verbose shows me the error:

@cekerholic, could you paste the stylesheet that causes this?

[cekerholic]

Here's link to my SASS files: https://github.com/cekerholic/MiddleStart/tree/master/source/assets/css

[porada]

Does v2.2.0 fix anything for you, guys?

[stephen-puiszis]

It took me a while to find this but I'm having the exact same issue @thenathanjones described with every other page refresh not loading my css. Every other request displayed this console error:
GET http://localhost:4567/stylesheets/screen.css?body=1 500 (Internal Server Error). I'm having the same issues with v2.1.2 and v2.2. Removing autoprefixer fixes the refresh problem.

[roytomeij]

Same here, on 2.2.0 with Middleman 3.3.5 on Ruby 2.1.2.

[porada]

@tdreyno, could you look at this? This bug must have been introduced together with your Rack magic (#6)—every second request fails with a 500. Tried this line:

headers.delete('Content-Length') if status == 304

Doesn’t seem to help, though.

[tdreyno]

@porada Will track this down today. Does this only happen with Sprockets involved? ?body=1 makes me think so.

[tdreyno]

This was a "bug" in middleman-sprockets. Sprockets now wants to be as fast as possible and returns 304 statuses instead of the full file content (even in dev mode). Downstream middleware needs the full content to rewrite so this doesn't work. Hard-coded this HTTP caching off in the latest middleman-sprockets which is v3.3.9. Please bundle update middleman-sprockets.

[porada]

Thank you. 🍻

[judewang]

@tdreyno, using middleman-sprockets v3.3.9 solved the issue, but I found it will create images from the bower_components folder to build folder. I found the issue will happen since v3.3.7, and we can not use middleman-autoprefixer v2.2.0 with midddleman-sprockets v3.3.6 without internal server error. Could you look at this? Thanks.

[tdreyno]

@judewang Yes, this is a known issue with middleman-sprockets v3.3.7. We're looking into it.
