DuoLun conversation has response content, but log shows no response message output

Issue: The multi-turn conversation has response content logs but no output of response messages, as shown in the image.

Attempted Solution: Modified the .env configuration as follows:

CODE_MAX_STRING_LENGTH=800000
TEMPLATE_TRANSFORM_MAX_LENGTH=800000
SANDBOX_WORKER_TIMEOUT=300
CODE_EXECUTION_READ_TIMEOUT=300
However, the issue persists.

Please provide a solution to this problem. Thank you.
