Application's State type error

[Ettapp]

function myFunction(app: Application) {
    // ...
}
const app = new Application({ state: { foo: 'bar' }})
myFunction(app)
//         ^^^

In this code, the app constant given to myFunction will be flagged with the following type error:

Argument of type 'Application<{ foo: string; }>' is not assignable to parameter of type 'Application<Record<string, any>>'.
  Types of property '#composedMiddleware' are incompatible.
    Type '((context: Context<{ foo: string; }, { foo: string; }>) => Promise<unknown>) | undefined' is not assignable to type '((context: Context<Record<string, any>, Record<string, any>>) => Promise<unknown>) | undefined'.
      Type '(context: Context<{ foo: string; }, { foo: string; }>) => Promise<unknown>' is not assignable to type '(context: Context<Record<string, any>, Record<string, any>>) => Promise<unknown>'.
        Types of parameters 'context' and 'context' are incompatible.
          Type 'Context<Record<string, any>, Record<string, any>>' is not assignable to type 'Context<{ foo: string; }, { foo: string; }>'.
            Type 'Record<string, any>' is not assignable to type '{ foo: string; }'.

Despite the probable simplicity of the error, I could't find a way to fix it. I'll try a bit longer but if anybody find it, a pull request will save my day x)

One way to make the error vanish:

const app = new Application<Record<string, unknown>>(...)

It does not solve the issue but masks the symptom away

I closed the issue thinking I found the problem but I was mistaken
