I had a similar error: Unexpected token < in JSON at position 0. I solved it by uninstalling yarn, reinstalling yarn, deleting the node_modules directory in this project, and then running yarn install.

I got the idea from this comment in the graphql-yoga repo but I don't yet understand why upgrading yarn fixed the error. Before upgrading yarn I was using yarn 1.1.0 and now I am using yarn 1.5.1.

Getting error "Unexpected token P in JSON at position 0" (I'm using a different setup, but I'm also using Apollo and Graphql playground". Interestingly, when I copy curl from playground, the request executes successfully. It must be some Grapqhl Playground issue
