[udaykor]

This issue pertains to the following package(s):

• [ ] GraphQL Playground - Electron App
• [ ] GraphQL Playground HTML
• [x] GraphQL Playground
• [ ] GraphQL Playground Express Middleware
• [ ] GraphQL Playground Hapi Middleware

What OS and OS version are you experiencing the issue(s) on?

Mac OS X Catalina

What version of graphql-playground(-electron/-middleware) are you experiencing the issue(s) on?

1.16.12

What is the expected behavior?

My schema is valid, I can query & mutate. I can look at docs. However when I select the schema tab, the browser reloads to a blank page. I have introspection set to true.

What is the actual behavior?

I should be able to look at the schema from GQL Playground

What steps may we take to reproduce the behavior?

I am using these to get to the GQL Playground
"graphql-tag": "^2.10.3",
"graphql-yoga": "^1.18.3",

This also happens for me. For some reason it seems like all lines that should be type *typename* {are just missing.

I found using Apollo-Server-Express to solve this. Now more graphql-yoga for me!
