fix: replace deprecated asyncio.get_event_loop() with get_running_loop()

[kratos0718]

Summary

asyncio.get_event_loop() is deprecated when there is no running event loop and emits a DeprecationWarning from Python 3.10 onwards. Per the official Python docs:

Deprecated since version 3.10: Deprecation warning is emitted if there is no current event loop. In future versions of Python this will be raised as a RuntimeError.

Both call sites in this fix are inside async def coroutines that are guaranteed to have a running loop, so asyncio.get_running_loop() is the correct replacement.

Affected call sites

• crewai/tools/structured_tool.py — CrewStructuredTool._arun falls back to running a sync self.func in the executor when the function is not a coroutine. Also removed a redundant inline import asyncio since the module is already imported at the top of the file.

• crewai_tools/tools/snowflake_search_tool/snowflake_search_tool.py — SnowflakeSearchTool._get_connection runs self._create_connection in the executor when no pooled connection is available.

Behavior

No behavior change. run_in_executor semantics are identical between the two loop accessors when a running loop is present (which is the case in both contexts here, since both are inside async def and the surrounding code already uses await). The only difference is the deprecation contract.

Note

I noticed this is the same pattern that was fixed in agno PR #8111 — keeping crewAI ready for Python versions that promote the warning to an error.

📝 Walkthrough

Walkthrough

Two async methods are updated to use asyncio.get_running_loop() instead of asyncio.get_event_loop() when scheduling synchronous executor calls. SnowflakeSearchTool._get_connection and CrewStructuredTool.ainvoke both adopt this pattern to ensure correct event loop handling within async contexts.

Changes

Event loop accessor migration

Layer / File(s)	Summary
Migrate to get_running_loop in async executor scheduling lib/crewai-tools/src/crewai_tools/tools/snowflake_search_tool/snowflake_search_tool.py, lib/crewai/src/crewai/tools/structured_tool.py	SnowflakeSearchTool._get_connection and CrewStructuredTool.ainvoke both replace asyncio.get_event_loop() with asyncio.get_running_loop() when scheduling synchronous thread-pool executor work, preserving the same callable behavior while fixing event loop acquisition.

🐰 A loop runs true, we took the wheel,
From old to new with async zeal,
Two paths align, one pattern clear,
Running loops through executors here! ✨
