Property 'default' of type 'Response | undefined' is not assignable to string index type 'Response'

using package open-api in a project with "strict": true in tsconfig.json causes the error:

Property 'default' of type 'Response | undefined' is not assignable to string index type 'Response'

It would seem that explicitly accepting undefined in ResponsesObject fixes it:

  export interface ResponsesObject {
    [index: string]: Response | undefined;
    default?: Response;
  }

This happens since version 9.0.0

@jsdevel I don’t mean to be pushy, but if there is any chance that you could take a look at the linked PR, it would be really helpful. For the moment, we are blocked to update to 9.0.2 because of this.

Thank you for your hard work!

default is definitely optional, therefore default?: Response is required.

IMHO, [index: string]: Response | undefined is reasonably, since you will not get a Response object back for a random string, e.g., resp['bla'] or resp.hello … therefore, you should be “forced” to check for undefined…
