wrong behavior with patch custom object

[caffeinism]

kubernetes version: 1.18.5
kubernetes_asyncio version: lastest

in kubernetes_asyncio

    async with ApiClient() as api_client:
        custom_object = CustomObjectsApi(api_client)
        return await custom_object.patch_namespaced_custom_object(
            group=API_GROUP,
            version=VERSION,
            plural=RESOURCE,
            name=name,
            namespace=namespace,
            body=patch,
        )

in kubernetes official python library

    with ApiClient() as api_client:
        custom_object = CustomObjectsApi(api_client)
        return custom_object.patch_namespaced_custom_object(
            group=API_GROUP,
            version=VERSION,
            plural=RESOURCE,
            name=name,
            namespace=namespace,
            body=patch,
        )

expect the same behavior, but get an error on kubernetes_asyncio.

Is this a version compatibility issue with kubernetes?

No, it's a known issue - openapi-generator doesn't support some type of patch which are used by K8s. Libraries work differently as you noticed.

I close this issue, please watch #68
