GraphQL Error Unknown argument slug

[3CordGuy]

Hey everyone. Trying to wire up contentful to a blog using the advanced starter. I've pulled out the filesystem plugins from the mix and am trying to just get a sample post pulled over. However, I'm currently getting an error GraphQL Error Unknown argument slug on starting develop server.

exports.createPages = ({ graphql, boundActionCreators }) => {
  const { createPage } = boundActionCreators
  return new Promise((resolve, reject) => {
    graphql(
      `
      {
        allContentfulBlogPost(limit: 1000) {
          edges {
            node {
              id
              slug
            }
          }
        }
      }
    `
    )
      .then(result => {
        if (result.errors) {
          reject(result.errors)
        }
        const postPage = path.resolve("src/templates/post.jsx");
        _.each(result.data.allContentfulBlogPost.edges, edge => {
          console.log(edge.node);

          createPage({
            path: `/post/${edge.node.slug}`,
            component: postPage,
            context: {
              id: edge.node.id,
              slug: edge.node.slug
            },
          })
        })
      })
      .then(resolve)
  })
}

I have context set to include "slug" which, if I understand correctly, is where it becomes available to the actual post component graphQL query... but it's throwing the error.
Here's some of my console output where this happens

   4 |       title
   5 |       slug

I'm pretty new to GraphQL so i could be missing something obvious here. Anything out of the ordinary from what you can see here? Thanks for looking!

It's possible a node doesn't have a slug perhaps?

Well, i only had one node/post in Contentful.

Hmm.. I ended up changing the query while it was running from allContentfulBlogPost to contentfulBlogPost and it works now... But, being so new to GraphQL, I'm not sure I understand the difference.

Oh right, yeah, that query wouldn't have worked. Make sure to try out your queries in GraphiQL before adding them to your components.

"all" is for querying all nodes of a type. Without all is for querying a single item.
