Mono repo (lerna) MiddlewareError: Type generator exists in middleware but is missing in Schema.

[Bram-Zijp]

I am working with a mono repo using "lerna". I ended up creating my shield rules for two endpoints in one module and import this module as dependency in the endpoint projects. When I imported the the rules initialized with shield from a dependency, I would get this error: MiddlewareError: Type generator exists in middleware but is missing in Schema..

To solve this problem I ended up doing this:

export const permissions = (passedShield: typeof shield) =>
  passedShield({
    ...
  });

@Bram-Zijp this often occurs due to version mismatch with graphql-middleware. I hope you've solved your problem 🙂
