I'm not sure if this thread is dead, but I've got this working with GraphiQL with the following minimal patch: https://github.com/andyvanee/graphql-lua/commit/478594100f129641417ec802bde1b0ec0c9597ca

Also, I was a bit confused since the only available version on luarocks is the 0.0.2 tag, which is quite old and does not include many of the changes necessary to work with GraphiQL - particularly https://github.com/bjornbytes/graphql-lua/commit/119aafe825e6158c461d2b24f4710beb22bc85cb . Perhaps it's time for an updated tag?

Thanks!
