Issue with partials\helpers\image.html. [asset] image="image.png" breaks the site.

Is this a BUG REPORT or FEATURE REQUEST?: bug

What happened: I have content/_index/services.md list fragment with front matter parameter section = blog. In content/blog/chocolate/ I have content fragment index.md and an image image.png.

Hugo throws an error when I set an image in fragment index.md, like so:

[asset]
  image = "image.png"

Here are the errors I get

What you expected to happen: I expected to see a thumbnail image for the blog post in the list fragment on my homepage. How to reproduce it (as minimally and precisely as possible):

You can reproduce this issue with my repo by uncommenting

[asset]
  image = "image.png"

in content/blog/chocolate/index.md Anything else we need to know?: I tried Hogo versions 0.58.3 and 0.59.1. Both throw the same error. I fully rely on themes build in partials. I do not have any custom partials. Environment:

• Syna Theme version: v0.15.2
• Hugo version:

Hugo Static Site Generator v0.59.1/extended windows/amd64 BuildDate: unknown
GOOS="windows"
GOARCH="amd64"
GOVERSION="go1.13.1"

I recommend using WSL and building on Linux or using WSL for production as well. Supporting Windows is kinda hard and time consuming since none of us have a Windows development environment. We will investigate the issue given the chance. We are always happy to receive Pull Requests to improve our Windows support. I’m sorry for the inconvenience.

To add a last comment for now. We mainly support linux based systems. We’ll leave this open to track and figure out what’s the culprit over the long term. Assuming it might be due to our fragment logic, that adds “/” separators that are linux only.
