@KyleAMathews Don’t understand why this one is closed... It’s still a bug at least 6 people had and it just wasn’t solved by anyone until now

[KyleAMathews]

👍 cool — just closed 400 so might have closed a few that shouldn't have.

I am seeing different issue related to GraphQL:

The GraphQL query from C:/dev/sandbox/path-with-ä-ру/src/components/image.js failed.

Errors:
  Syntax Error: Cannot parse the unexpected character "\u0420".

        fluid(maxWidth: 300) {
          ...GatsbyImageSharpFluid
        }
      }
    }
  }

  fragment GatsbyImageSharpFluid on ImageSharpFluid {

Feels like we need to slugify the query name. Does that sound right @vladar ?

[vladar]

Yep, do we use any library for this already? Or maybe you have one in mind?

Should be fixed in gatsby 2.17.17
