We use issues\nfor bug reports and feature requests. Please find us at https://slack.crossplane.io\nfor questions, support, and discussion.\n--\u003e\n\n### What happened?\n\nThe `serve` function accepts a `grpcv1.FunctionRunnerService`, when it should accept a `grpcv1.FunctionRunnerServiceServicer`.\n\nhttps://github.com/crossplane/function-sdk-python/blob/ad6f1e1c18b6cd698465cfb3cb624f6acc73fcdf/crossplane/function/runtime.py#L72-L79\n\nThis results in a type mismatch:\n\n```bash\nMethod \"RunFunction\" overrides class \"FunctionRunnerService\" in an incompatible manner\n  Base method is declared as a staticmethod but override is not\n  Positional parameter count mismatch; base method has 10, but override has 3\n...\n```\n\nSimilarly, a class that implements a RunFunction(Service) servicer, should really implement `grpcv1. FunctionRunnerServiceServicer` instead.\n\nhttps://github.com/crossplane/function-sdk-python/blob/ad6f1e1c18b6cd698465cfb3cb624f6acc73fcdf/crossplane/function/runtime.py#L137-L148\n\nSee gRPC docs for details: https://grpc.io/docs/languages/python/quickstart/#update-the-server\n\n### How can we reproduce it?\n\u003c!--\nHelp us to reproduce your bug as succinctly and precisely as possible. Artifacts\nsuch as example manifests or a script that triggers the issue are highly\nappreciated!\n--\u003e\n\nLook at the signature of respective class and you'll see the mismatch.\n\n### What environment did it happen in?\nFunction version: v0.13.0\n\n\u003c!--\nInclude at least the version or commit of Crossplane you were running. Consider\nalso including your:\n\n* Cloud provider or hardware configuration\n* Kubernetes version (use `kubectl version`)\n* Kubernetes distribution (e.g. Tectonic, GKE, OpenShift)\n* OS (e.g. from /etc/os-release)\n* Kernel (e.g. `uname -a`)\n--\u003e\n","author":{"url":"https://github.com/eric-carlsson","@type":"Person","name":"eric-carlsson"},"datePublished":"2026-06-09T10:29:46.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/211/function-sdk-python/issues/211"}
