你好，@lingfengchencn！很高兴再次见到你，希望你一切都好。

The error you're encountering seems to be related to a misconfiguration or network issue preventing your application from communicating with the code execution service. This is a common issue when the application is unable to reach the code execution service, possibly due to incorrect settings or network problems.

A similar problem was resolved by changing the connection address to http://host.docker.internal:19530/ instead of using 127.0.0.1:19530, ensuring that Docker's WSL 2 based engine is configured to add *.docker.internal names to the host's etc/hosts file. This adjustment was effective for users experiencing connectivity issues with the code execution service.

Make sure that your CODE_EXECUTION_ENDPOINT and CODE_EXECUTION_API_KEY environment variables are correctly configured. These variables should match the settings expected by your code execution service. Additionally, verify that the code execution service is running and accessible from your application.

Here's a snippet to help you handle exceptions in your code_executor.py more effectively:

try:
    response = post(str(url), json=data, headers=headers, timeout=CODE_EXECUTION_TIMEOUT)
    if response.status_code == 503:
        raise CodeExecutionException('Code execution service is unavailable')
    elif response.status_code != 200:
        raise Exception(f'Failed to execute code, got status code {response.status_code}, please check if the sandbox service is running')
except CodeExecutionException as e:
    raise e
except Exception as e:
    raise CodeExecutionException('Failed to execute code, this is likely a network issue, please check if the sandbox service is running')

This code ensures that any issues with the code execution service are correctly identified and reported, helping you diagnose the problem more effectively.

If after these adjustments the issue remains, it would be beneficial to check both the application and service logs for more detailed error messages that could provide further insight into the problem.

Unfortunately, without specific details on the changes made in Dify version 0.6.0, I recommend checking the release notes or changelog for any updates that might impact your application.
