The schema of your project is published under the API endpoint with the name /schema.graphql. if your API endpoint is the GraphQL schema is located at

Schema for Consumers

The schema is used for consumers to update types, queries & mutations.

By default the schema is secured by the same firewall of the API endpoint. If your API require credentials, then must be used to access to the schema too. In a local environment when you need access to your own API (developing a frontend UI) this can be annoying because you need update the schema every time.

In this scenario can disable the symfony firewall to schema in dev environment.


            pattern:   ^/(?!explorer|login|schema.graphql)
            stateless: true
            provider: fos_userbundle
                    - lexik_jwt_authentication.jwt_token_authenticator

        - { path: ^/schema.graphql,  roles: IS_AUTHENTICATED_ANONYMOUSLY, allow_if: %kernel.debug% }
        - { path: ^/login,  roles: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/explorer,  roles: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/,       roles: IS_AUTHENTICATED_FULLY }

Note the allow_if: %kernel.debug% in the schema access_control rule, is very important to avoid publish your schema without credentials in production too.
