Can some one look in to it , its little urgent @maticzav

[Matic Zavadlal]

@kamarajuPrathi we offer priority support, you know 😉 . You could compose a CodeSandbox outlining your problem, and I'll see what I can do. With current information I cannot do anything.

@maticzav basically its missing permissions type from schema . How do we ensure the we get that permissions on the schema ?
I am doing

const { applyMiddleware } = require("graphql-middleware")
const { makeExecutableSchema } = require("graphql-tools")
const { rule, shield } = require("graphql-shield")

const isAuthenticated = rule()(async (parent, args, ctx, info) => {
  return ctx.user
})

// Construct a schema, using GraphQL schema language.
let typeDefs = gql
  type Query {
    hello: String
  }


const resolvers = {
  Query: {
    hello: () => "Hello world!",
  },
}

const permissions = shield({
  Query: {
    hello: isAuthenticated,
  },
})

const schema = applyMiddleware(
  makeExecutableSchema({
    typeDefs,
    resolvers,
  }),
  permissions,
)

const server = new ApolloServer({
  schema,
})

exports.graphql = server.createHandler()

The error i am getting from graphql-middleware

import { IMiddleware } from './types'
import { isMiddlewareFunction } from './utils'

export function validateMiddleware<TSource, TContext, TArgs>(
  schema: GraphQLSchema,
  middleware: IMiddleware<TSource, TContext, TArgs>,
): IMiddleware<TSource, TContext, TArgs> {
  if (isMiddlewareFunction(middleware)) {
    return middleware
  }

 const types = schema.getTypeMap()

  Object.keys(middleware).forEach(type => {
    if (!Object.keys(types).includes(type)) {
      throw new MiddlewareError(
        `Type ${type} exists in middleware but is missing in Schema.`,
      )
    }```
@maticzav below are the libraray versions i use 
"apollo-server-lambda": "~2.9.16",
    "graphql": "~14.5.8",
    "graphql-import": "~0.7.1",
     "graphql-middleware": "^4.0.2",
    "graphql-shield": "^7.0.11"

@kamarajuPrathi Did you solve this?

[Matic Zavadlal]

@joeyfigaro check that you don't have any type mismatches with your dependencies.
