[Typing Error] GraphQL Schema Stitching - Part 6 (YouTube)

[valdeniomarinho]

Hey Ben, thanks for the project, very helpful!

I'm getting a type error exactly at this point. Probably is some conflict between schema property from GraphQLServer and the type returned by mergeSchemas() from graphql-tools.

Snippet

const schemas: GraphQLSchema[] = []

  const folders = fs.readdirSync(path.join(__dirname, './modules'))

  folders.forEach((folder) => {
    const { resolvers } = require(`./modules/${folder}/resolvers`)
    const typeDefs = importSchema(
      path.join(__dirname, `./modules/${folder}/schema.graphql`)
    )

    schemas.push(makeExecutableSchema({ resolvers, typeDefs }))
  })

  // GETTING ERROR ON THIS NEXT LINE
  const gqlServer = new GraphQLServer({ schema: mergeSchemas({ schemas }) })
