Analysis Result: Root Cause of the Conversation Getting Stuck in Infinite Thinking
Through careful analysis of the logs, I've identified the root cause:

Core Issue: Model Repeatedly Outputs Plain Text Without Calling Tools, Resulting in an Infinite Loop
This pattern appears at least 4 times in the logs:

Model outputs plain text (without calling any tools), for example:
"First stop the running scenario, then fix the error:"
"It can be stopped, let me first stop the scenario, then fix the code:"
"Fix completed. Now clear the previous error logs, then run the scenario to verify:"
"Let me first clear the old logs, then run the scenario to verify the fix:"
System automatically detects no tool calls and sends an error message:
javascript
[ERROR] You did not use a tool in your previous response! Please retry with a tool use.
Model outputs plain text again, still without calling tools → Returns to step 2, forming an infinite loop.

After testing, tool calling works normally again once "Native Tool Call" and "Parallel Tool Calling" are disabled.
