Validate introspection response

[dim-37]

I tried to validate my introspection.json file with graphql-inspector from npm and it returns an error Error: Unable to read JSON file: FILE_PATH: Syntax Error: Expected <EOF>, found Name "kind"..
How can I find json schema for graphql schema to validate it or can somebody recommend me a tool to validate introspection?

I don't understand what is wrong whit it :

introspection.zip

seems like you have an invalid JSON. maybe graphql-js repo can help you?
