              services: {
                // The service-specific options by the name of the service
              },
            },
          },
        ],
      },
    },

What you did: Installed the plugin

What happened: The embedding feature didn’t work

Problem description: I’m using gatsby-transformer-remark and I’ve added the gatsby-remark-embedder to the plugin array. I’ve left 2 empty lines between the url in my markdown. When I open the page the url is just a string and no embedding has happened.

I cleared the Gatsby cash and I put a console.log statement on top of the main function of the plugin(through node_modules) but nothing was logged. My opinion is that gatsby-transformer-remark doesn’t call the gatsby-remark-embedder. The gatsby-transformer-remark works fine because I use it for other things.
