graphql-playground: Urgent, Prisma playground broken, Uncaught SyntaxError: Unexpected end of input

I’m using a Prisma server, and I’m using the playground included in my browser. I’m getting the following error: Uncaught SyntaxError: Unexpected end of input

The error is being thrown from the following file:

http://cdn.jsdelivr.net/npm/graphql-playground-react/build/static/js/middleware.js

All of my GraphQL playgrounds are broken across localhost and a few live Prisma server instances
