Get introspective schema on client side

[nerdyator]

Hello Team,

Im trying to get introspective schema on my android client. for that Im using following command.
apollo-codegen download-schema http://swapi.graphene-python.org/--output schema.json

But it returns me following error:
error: Error while fetching introspection query result: invalid json response body at http://swapi.graphene-python.org/ reason: Unexpected token < in JSON at position 1

I require schema.json at client side to query the server.

Kindly guide.
Thank you.

I'm late to this, but you're trying to get a JSON response from an HTML landing page.

Try the same action on the actual GraphQL endpoint: http://swapi.graphene-python.org/graphql
