Compiler errors at schema description

[marcotoniut]

While using another tool to generate the schema, I found out that the relay compiler errors whenever there's a string description above the topmost schema declaration.

"Description of the schema"
schema {
  query: RootQueryType
  mutation: RootMutationType
}

yields

ERROR:
Syntax Error: Expected "schema", found String "Description of the schema"
error Command failed with exit code 100.

After digging around for a bit, I found out that there has been a spec update to graphql which incorporates the ability to add descriptions at this level. Am I right to assume that relay is still catching up to it?

From what I can tell, this was added to graphql-js Feb 2nd and they have not yet cut a release that includes it. I have confirmed that this parses without error in the new Rust compiler.

If graphql-js cuts a new release with this change, and it's within the v15 range, you should be able to resolve this by upgrading your version of graphql-js since Relay expects it as a peer dependency.
