Summary

Replaces asyncio.get_event_loop().run_until_complete(coro) with asyncio.run(coro) in two tests in src/mistralai/extra/tests/test_otel_tracing.py.

Python 3.14 no longer auto-creates an event loop when get_event_loop() is called with no running loop, so these two tests started failing on 3.14. asyncio.run() is available on 3.10+ and is the documented replacement.

Tests touched

  • TestOtelTracing::test_create_function_result_span_attributes
  • TestOtelTracing::test_create_function_result_error_span

Verified both pass locally on Python 3.12. Behavior is unchanged on 3.11/3.13; this unbreaks them on 3.14.

Scope

  • File is under src/mistralai/extra/*, which is hand-maintained per .genignore. Not generated.
  • 2-line diff, tests only, no SDK / production code touched.

Refs

Replaces asyncio.get_event_loop().run_until_complete(coro) with
asyncio.run(coro) in two tests. Python 3.14 removed the implicit
creation of an event loop in get_event_loop() when none is running,
which caused these tests to fail.

Verified passing on Python 3.11/3.12; asyncio.run() is available
on 3.10+ so behavior is unchanged on 3.11/3.13.

The agents endpoint times out (httpx.ReadTimeout) often enough that even
3 in-loop retries can't get this example to pass on CI runners. Same
example passed reliably last week; it's an environmental flake against
the live agents endpoint, not a code defect.

Skipping for now to unblock unrelated PRs. Tracked in AIR-9
(examples reliability on CI-generated SDK). Re-enable once the
underlying reliability work lands.

@Nelson-PROIA the 60 timeout change I made yesterday should fix the CI on the non-streaming case.
