Cannot read property 'replace' of undefined

You need to pass in a slug value for this plugin to work.

In your case, you can simply rename it as so:

slug: uid

or

slug:path

This should do the job. I will update the Readme to make sure, this is mentioned. Thanks for pointing it out!

Looks like it's an issue with

var slug = source === "allMarkdownRemark" || source === "allMdx" ? node.fields.slug.replace(/^\/|\/$/, "") : node.slug.replace(/^\/|\/$/, "");

I don't have slug in my query

How do we get round the issue of having sub elements?
allImageSharp { edges { node { id original { src } } } }

I'm trying to retrieve all images throughout the site. I can obviously alias original as

slug:original

but then the code will error as it's looking for node.slug.replace

HI, I can do this for other queries but for images it's another sub level

THis works

allSitePage {
              edges {
                node {
                  id
                  slug: path
                }
              }
            }

but for images the query is

allImageSharp {
    edges {
      node {
        fluid {
          slug: src
        }
      }
    }
  }

or

allImageSharp {
    edges {
      node {
        slug: fluid{
           src
        }
      }
    }
  }

which means it's still an extra level

[GreatState]

. I was under the impression the slug had to be the URL of the image or resource?

[GreatState]

I've got a bit further with it by detecting allImageSharp query
var slug = source === "allMarkdownRemark" || source === "allMdx" || source === "allImageSharp" ? node.fluid.slug.replace(/^\/|\/$/, "")

which seems to generating the xml now but the buikld breaks

rror: TypeError [ERR_INVALID_ARG_TYPE]: The "url" argument must be of type string. Received type undefined

Okay. I've realised why i think. Images need to be in a different format

<url>
       <loc>https://example.com/mens-hats</loc>
       <lastmod>2018-10-12</lastmod>
       <image:image>
          …
       </image:image>
    </url>

Looks like you can't link directly to an image in the url element?

Anyway of supporting images used on a page?
