Unexpected error during execution

Error message

Unexpected error during execution: {str(e)}

What it means

Catch-all for any non-ServerError exception during Aliyun code execution — covers SDK client-side failures (serialization of arguments, enum mismatch), local parsing of the structured result, and network errors that do not surface as ServerError. The original exception text is embedded.

Solutions

1. Read str(e) to classify: connection errors mean the instance is gone — recreate it; parse errors mean SDK/result-shape drift.
2. Ensure `arguments` contains only JSON-serializable values.
3. Pin the agentrun-sdk version tested with this provider.
4. Verify the instance still exists (or just recreate) before retrying execution.

try:
    result = provider.execute_code(instance_id, code, "python", timeout=10)
except RuntimeError as e:
    msg = str(e).lower()
    if "not exist" in msg or "connect" in msg:
        instance = provider.create_instance("python")  # dead sandbox: recreate and retry
        result = provider.execute_code(instance.instance_id, code, "python", timeout=10)
    else:
        raise

When it happens

Trigger: execute_code when: the arguments dict cannot be serialized into the runner format, the agentrun-sdk version changed result shapes and the structured-result parsing breaks, Sandbox.connect to a dead instance raises, or the response JSON is not a dict as expected.

Common situations: instance_id points to an already-destroyed sandbox; SDK version drift (the file notes CodeLanguage enum changes around 0.0.26); non-JSON-serializable values inside arguments; transient connectivity loss mid-request.
