Prisma

I am trying to disable the playground on my prisma service as well as graphql-yoga server, but not having much luck. I am passing the following setting `playground: process.env.DISABLE_PLAYGROUND ? false : '/',` into `new GraphqlServer` and deploying to now.sh, but i can still access the playground via <https://labs-prisma-fedgrhwoff.now.sh/>

and passing in the ENV var in my `now.json` file as follows:
```"env": {
    "DISABLE_PLAYGROUND": "true"
  },```

Where did you read about this way to disable playground? Is there a forum post or docs? :slightly_smiling_face:

&gt; Defines the endpoint where you can invoke the Playground; setting to false disables the playground endpoint

i think im passing it into the wrong place

my bad. need to be passed as server.start() options
