Can't use GraphQL in a Heroku

[Bat-m]

Bug report

Trying to access /graphql via heroku instance

My goal was simply to access to http://www.host.com/graphql after deploy my strapi application via heroku

Expected behavior

Try to access /graphql endpoint after setup graphql on heroku even if graphql server parameters was affected

Code snippets

here you can find the parameters from config/plugin.js

module.exports = ({ env }) => ({
  
  graphql: {
    endpoint: '/graphql',
    shadowCRUD: true,
    playgroundAlways: true,
    depthLimit: 7,
    amountLimit: 100,
    introspection: true,
    apolloServer: {
      tracing: false,
    },
  },
});

Tested on a fresh v3.4.1 project and am unable to reproduce the issue:

@BaptisteMonet can you please provide reproduction steps?

@derrickmehaffy ok if it works for you I got a problem on my side

some log from heroku:
`2021-01-13T12:16:21.327713+00:00 heroku[router]: at=info method=GET path="/graphql" host=stj-api.herokuapp.com request_id=150d799c-3f06-4fac-86a3-e2a8881331ca fwd="91.168.104.73" dyno=web.1 connect=2ms service=54ms status=400 bytes=327 protocol=https

It seems your setting in the plugins.js file isn't taking effect as thats the default for GraphQL playground in production (doesn't exist)

Ahhh here is the problem

here you can find the parameters from config/plugin.js

It needs to be ./config/plugins.js not ./config/plugin.js

[derrickmehaffy]

https://strapi.io/documentation/developer-docs/latest/plugins/graphql.html#configurations

Path — ./config/plugins.js

[Bat-m]

can you show me a picture of your folder ?
not sure to understand where the config folder start.
here is mine

[derrickmehaffy]

I'm using the ./config/env/production/plugins.js but ./config/plugins.js also works (the env folder is optional but you should be using it with Heroku per our docs)

[derrickmehaffy]

Also sorry, I'm a linux user so the ./ is a common path expression meaning "current folder"

Note: It is changed from graphql to graphql.config

module.exports = {
    graphql: {
      config: {
        endpoint: '/graphql',
        shadowCRUD: true,
        playgroundAlways: true,
        depthLimit: 7,
        amountLimit: 100,
        apolloServer: {
          tracing: false,
        },
      },
    },
  };

    },
  };

Thanks! this is allowing me to see the GraphQL playground but I am getting a 400 once opened.

Will keep trying and post any solution here.
