Additional context

Look strange since because in the docs i see.

async function getSchema({ req }): GraphQLSchema {
  if (req.isAdmin) {
    return adminSchema;
  }

  return userSchema;
}

I see on the master branch

export const useLazyLoadedSchema = (schemaLoader: (context: Maybe<DefaultContext>) => GraphQLSchema): Plugin => {
  return {
    onEnveloped({ setSchema, context }) {
      setSchema(schemaLoader(context));
    },
  };
};

export const useAsyncSchema = (schemaPromise: Promise<GraphQLSchema>): Plugin => {
  return {
    onPluginInit({ setSchema }) {
      schemaPromise.then(schemaObj => {
        setSchema(schemaObj);
      });
    },
  };
};

setSchema seems to expect a GraphQLSchema not a Promise

@dotansimha I'm right?

[Moumouls]

after some investigation, it seems the source of the issue.

Error: Expected {} to be a GraphQL schema.

For parse-server we need promise support for useLazyLoadedSchema.

I think this is kind of resolved in the next major release we will remove useLazyLoadedSchema
