Unexpected value passed to handler when calling endpoint and not specifying the value for an array query parameter

[spinenkoia]

Calling an endpoint and not specifying the value for an array query parameter results in handler receiving ['']

For example , when requesting curl -i -X GET "http://127.0.0.1:8080/test?ids=" in the handler, instead of [] I get ["]

Steps to reproduce swagger.yaml

openapi: 2.0.0
info:
  version: 1.0
paths:
  /test:
    get:
      operationId: test_handler
      parameters:
        - name: ids
          required: false
          in: query
          type: array
          collectionFormat: csv
          items:
            type: string
            format: uuid
      responses:
        "200"

main.py

from typing import List

from aiohttp.web import Application, run_app
from aiohttp.web import Request, Response
from aiohttp_apiset import SwaggerRouter
from aiohttp_apiset.middlewares import jsonify
from aiohttp_apiset.swagger.operations import OperationIdMapping

async def test_handler(request: Request, ids: List[str]) -> Response:
    print(f"Received list: {ids}")

    return Response()

def main():
    router = SwaggerRouter(
        swagger_ui='/swagger/',
        search_dirs=['./'],
    )

    app = Application(router=router, middlewares=[jsonify])

    opmap = OperationIdMapping(test_handler=test_handler)

    router.include(spec='swagger.yaml', operationId_mapping=opmap)

    run_app(app)

if __name__ == "__main__":
    main()
