gatsby-source-graphql only absolute urls are supported - reactjs

Question

I'm integrating graphQL into my gatsby site. I am getting an error that says "only absolute urls are supported" and then points to some code in the node-fetch library. There isn't an obvious path to how I'm getting that code to execute though, so I'm not sure what the source of my issue is. I have done several days worth of searching, and while I have found several threads about this error, it's never been in the context of gatsby-source-graphql. Any help would be appreciated.
