W0901 16:58:07.005324   45203 factory_object_mapping.go:423] Failed to download OpenAPI (the server could not find the requested resource), falling back to swagger
error: error validating "test-deployment.yaml": error validating data: the server could not find the requested resource; if you choose to ignore these errors, turn validation off with --validate=false

--validate=false をつけると確かにapplyできるけれど。。。
