I've this line in schema.graphql:

# import some random text, doesn't matter from "./generated/prisma.graphql"

If I remove it, I get this error:

throw new Error("Field " + node.name.value + ": Couldn't find type " + nodeTypeName + " in any of the schemas.");

It's a bit weird as this line seems to be a comment, but I guess it's not. I imagine there is some regular expression out there and doesn't care about what's next "import"?
