Lots of warnings when generating the geofox gti api

When running openapi-python-client on the gti geofox api I get a lot of warnings:

$ openapi-python-client generate --url https://gti.geofox.de/v3/api-docs/public

Warning(s) encountered while generating. Client was generated, but some pieces may be missing

If you believe this was a mistake or this tool is missing a feature you need, please open an issue at https://github.com/openapi-generators/openapi-python-client/issues/new/choose

After generation, all the api files only contain sync_detailed and asyncio_detailed methods. sync and async methods are missing, e.g.:

$ grep def open-api-definition-client/open_api_definition_client/api/announcement_controller/get_announcements.py 
def _get_kwargs(
def _build_response(*, response: httpx.Response) -> Response[Any]:
def sync_detailed(
async def asyncio_detailed(

Is this a bug in your code or something I should report to Geofox?

$ openapi-python-client --version
openapi-python-client version: 0.11.1

Reproduce with openapi-python-client generate --url https://gti.geofox.de/v3/api-docs/public using version 0.11.1, then inspect the generated open_api_definition_client/api/announcement_controller/get_announcements.py and the other affected API files. Compare the Geofox response definitions with the generator's parsing behavior; done means the valid responses generate the expected convenience methods without the reported warnings, or the issue is shown to belong to Geofox's specification.
