How to describe Inclusion Filter Array as a query parameter?

[mikeevstropov]

Expecting something like @param.include() or an array of any described by oas in @param.
E.g. array should contain string or {"relation": "name", "scope": {...}}, so

async me(
  @param({
    name: 'include',
    in: 'query',
    content: {
      'application/json': {
        type: 'array',
        items: {
          type: 'any'
        }
      },
    },
  })
  include?: InclusionFilter[],
): Promise<User> {
  // GET /me?include=[{"relation":"role"}]
  // array passed to `include` always be a string
  console.log(include); // [{"relation":"role"}]
  console.log(typeof include); // string
}

Workaround by a redundant decorator @param.filter:

async me(
  @param.filter(User)
  filter?: Filter<User>,
): Promise<User | null> {
    const include = filter?.include;
}

Dirty workaround without scheme validation:

async me(
  @param.query.string('include')
  include?: string,
): Promise<User | null> {
  const inclusionFilters: InclusionFilter[] = include
    ? JSON.parse(include)
    : undefined;
}
