Description

If the default integer value is too high, namely above INT32_MAX (i.e. 2^31 - 1) the python-aiohttp generator produces a constructor with an incorrect, None signature. For values below 2^31 it works fine, the default is respected.

Specifying format: int64 doesn't help.

Example: with this object:

    Memory:
      type: object
      properties:
        ram_installed:
          type: "integer"
          default: 2147483647

the generated c-tor signature in openapi_server/models/memory.py is:

    def __init__(self, ram_installed: int=2147483647):

Bug: with this object:

    Memory:
      type: object
      properties:
        ram_installed:
          type: "integer"
          default: 2147483648

the generated c-tor signature in openapi_server/models/memory.py is:

    def __init__(self, ram_installed: int=None):

Steps to reproduce

Generate a server with python-aiohttp using docker.

❯ docker run --rm -v "$PWD:/local" openapitools/openapi-generator-cli generate \                                                                      
          -i /local/example.yml \
          -g python-aiohttp \
          -o /local/out/
