V4 - ApolloServer TSError Expected 0 type arguments but got 1.

[DanielPachecoAr]

I have the following code baesd on the migration examples from the apollo page.

import { ApolloServer } from '@apollo/server'; import { expressMiddleware } from '@apollo/server/express4';

  interface MyCustomContext {
    dataSources: MyDataSources;
    token: any;
  }

  const apolloServer = new ApolloServer<MyCustomContext>({
    typeDefs: schema,
    resolvers,
    plugins: [...],
    apollo: {
      key: APOLLO_KEY,
      graphRef: APOLLO_REF
    }
  });

await apolloServer.start();

  let server = expressMiddleware(apolloServer, {
      context: async ({ req }) => {
      let token = req.headers.token;
      return {
        dataSources: {
          .
          .
          .
        },
        token
      };
  }
  });

 return server;

From that code Im getting the following typescript compilation errors:

TSError: ⨯ Unable to compile TypeScript: index.ts:XX:41 - error TS2558: Expected 0 type arguments, but got 1.

XX   const apolloServer = new ApolloServer<MyCustomContext >({
                                                               ~~~~~~~~~~~~~~~~
index.ts:YY:22 - error TS2339: Property 'start' does not exist on type 'ApolloServer'.

YY   await apolloServer.start();

Im able to bypass these errors using:

// THIS // @ts-ignore const apolloServer = new ApolloServer({ typeDefs: schema, resolvers, plugins: [...], apollo: { key: APOLLO_KEY, graphRef: APOLLO_REF } }) as any; // AND THIS

And the serverworks, however Im hoping get some help in order not to use those workarounds.

BTW HERE is the ApolloServer definition, and I get to that file when ctrl+clicking the call on my code.

Massive, syntactically incorrect, and incomplete snippets don't really help me to get you to the bottom of your problem. Can you please send a codesandbox link or provide an actual reproduction that I can clone or run locally which demonstrates the issue in a concise way?

[DanielPachecoAr]

Will do ASAP, thanks for the quick response.

I suspect the version of typescript might be relevant (though that will also be clear from a self-contained reproduction).

I couldn´t manage to reproduce it in codesandbox, and it got fixed with a node update.
