TypeError: Cannot read property 'some' of undefined

I am getting the following error when building Typedefs in Apollo Server:

return typeDef.definitions.some(definition => definition.kind === language_1.Kind.DIRECTIVE_DEFINITION &&
                                   ^
TypeError: Cannot read property 'some' of undefined

I tried to follow some solutions from here #2961 but still, I am getting the error.

This is how I am creating the schema:

fs.readdirSync(__dirname)
 .filter(dir => { console.log('dir', dir); return dir.indexOf('.') < 0 })
 .forEach((dir) => {
    const tmp = require(path.join(__dirname, dir)).default;
    resolvers = merge(resolvers, tmp.resolvers);
    typeDefs.push(tmp.types);
 });

const schema = new ApolloServer({
  typeDefs,
  resolvers, 
  playground: {
    endpoint: '/graphql',
    settings: {
      'editor.theme': 'light'
    }
  }
});

Version:

    "apollo-server-express": "^2.18.2", 
    "graphql-tools": "^6.2.4",

I opened this repo to reproduce the error https://github.com/chrisjaimes/apollo-server-error. What could I be missing?
