[Bug] ENDLESS LOOP in google-adk==1.20.0 when I use code executor

[feiniaoshizhe]

Describe the bug

When I use the code executor, the llm call can get stuck in an ENDLESS LOOP and not to exit
But, this issue emerged after upgrading to Google ADK 1.20.0 and was not present in version 1.19.0

Notably, I used traces to track llm calls and found that there were no tool outputs after using the code executor.

In version 1.19.0, llm call has code executor output

In version 1.20.0, llm call only has code executor input

Versions

• OS: Windows
• ADK version: 1.20.0
• Python version: 3.11

Experiencing the same here, it seems all outputs from any code executor are not passed to the LLM at all in 1.20, but it all works in 1.19.

@feiniaoshizhe Thanks for reporting this!
Could you please share a small code example that reproduces the issue, along with details about the model you’re using and how the code executor is configured? Logs or trace output in text form showing the repeated LLM or tool calls would also help us understand why it gets stuck in a loop.
Thank you.
