CODE_EXECUTION_TIMEOUT_ERROR

Error message

Code execution timeout

What it means

CODE_EXECUTION_TIMEOUT_ERROR is raised by _handle_error_response when the iFly v2 code service responds with type == 'exec_code_timeout', meaning the sandbox killed the user's code because it exceeded its execution time budget. The err_msg is the fixed string 'Code execution timeout'.

Solutions

1. Optimize or shorten the code in the code node: vectorize loops, remove sleeps, add internal timeouts to network calls.
2. Split the work into multiple code nodes or process data in chunks.
3. Raise the code-execution timeout limit in the executor/sandbox configuration if legitimate long runs are expected.
4. Fix the root cause if an upstream node change made a loop non-terminating (e.g. unexpected empty input).

Example fix

# before (inside user code node)
while True:
    process(rows)
// after
import itertools
for _ in itertools.islice(iter_process(rows), MAX_ITERATIONS):
    pass

# static sanity check before submitting user code
import ast
tree = ast.parse(user_code)
if any(isinstance(n, ast.While) for n in ast.walk(tree)) and "break" not in user_code and "return" not in user_code:
    raise ValueError("while loop without break/return likely exceeds execution timeout")

try:
    output = await executor.execute(...)
except CustomExceptionCD as e:
    if e.err_code == CodeEnum.CODE_EXECUTION_TIMEOUT_ERROR.code:
        logger.error("code node exceeded time budget; chunk the workload")
        output = partial_result_or_empty

When it happens

Trigger: A code node whose script runs longer than the sandbox's time limit — infinite loops, very large data processing, long sleeps, or blocking network calls without timeouts inside the user code.

Common situations: Users paste heavy data-wrangling scripts into code nodes; a loop that never terminates after an upstream node changed its output shape; sandbox timeout lowered via config making previously-fine scripts fail.

Understand the failure class

Background: Request timed out: what client-side request timeouts mean across libraries (Request timed out, TIMED_OUT, APITimeoutError) — this error's family across 39 libraries.

• Timeouts: ETIMEDOUT, deadlines, and hung requests — what actually expires when a request times out.
