withPrefix not working in 2.0.118

[morleytatro]

Description

Files inserted in the static folder and referenced using withPrefix are not found in development.

Steps to reproduce

Start a new Gatsby project with 2.0.118 and use the withPrefix to load an assets

Expected result

The asset should be successfully called in development.

Actual result

It instead rendered a 404 page. I confirmed that this was not the case in version 2.0.114.

Can you provide reproduction sample for this?

I tried reproducing locally but it seems to work for me using gatsby@2.0.118 (I used /blog as pathPrefix):

Did you build using gatsby build --prefix-paths?

[morleytatro]

Strange, it actually wasn't during the build that I noticed it; it was in development. However, upon starting a brand-new repo with 2.0.118, the issue isn't happening. I have a pathPrefix of '/'. Unfortunately, I can't share the code, so I'll close this for now until I determine what the pertinent difference is.
