[BUG] Code node output always contains an error field, even when execution is successful

[breilian]

Description

When executing a code node, the output consistently includes an error field, even if the node executes successfully and the entire pipeline passes. This behavior is misleading and may cause unnecessary confusion during debugging or monitoring.

Preconditions

• Environment: DEV
• The pipeline contains a code node with structured output enabled.

Steps to Reproduce

1. Deploy the following pipeline YAML to the DEV environment:

   state:
     some_data:
       type: str
       value: ''
   entry_point: error_test
   nodes:
     - id: error_test
       type: code
       code:
         type: fixed
         value: '{"some_data": "any value from code node"}'
       output:
         - some_data
       structured_output: true
       transition: END

2. Execute the pipeline.
3. Observe the output of the error_test node.

Test Data

• Pipeline YAML: Provided above.
• Environment: DEV

Actual Result

The output of the code node includes an error field with the following content:

{
  "result": {"some_data": "any value from code node"},
  "error": "/lib/python3.13/site-packages/requests/__init__.py:113: RequestsDependencyWarning: urllib3 (2.5.0) or chardet (6.0.0.post1)/charset_normalizer (3.4.3) doesn't match a supported version!  warnings.warn(",
  "execution_info": "Execution time: 6.06s, Packages: chardet, requests"
}

Expected Result

The output of the code node should not include an error field if the node executes successfully. The expected output is:

{
  "result": {"some_data": "any value from code node"},
  "execution_info": "Execution time: 6.06s, Packages: chardet, requests"
}

Attachments

• N/A

Notes

• The error field appears to be populated by a warning from the requests library, specifically a RequestsDependencyWarning about mismatched versions of urllib3 and chardet/charset_normalizer.
• This issue may be related to the Pyodide sandbox environment or the alita_client injection process.
