Cause (Documented platform behavior): runCode uses two timers: requestTimeoutMs for the initial HTTP request and timeoutMs (default 60 000 ms) for streaming the execution; aborting yields the TimeoutError. If the connection closes and isRunning() reports false, the SDK instead reports the sandbox was killed and points to the sandbox-level timeoutMs/setTimeout. Fix status: documented_behavior Limitations: - Source is the published @e2b/code-interpreter 2.8.0 npm bundle; the Python package may use different defaults. - Related atlas records cover commands.run() timeouts and sandbox lifetime; this is the code-interpreter runCode timer. - Not reproduced in this session. Other error fragments: - The sandbox was killed while the request was in progress. This can happen when the sandbox times out or is killed manually. - You can provide context or language, but not both at the same time. Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/@e2b/code-interpreter/-/code-interpreter-2.8.0.tgz#package/dist/index.mjs (official_docs, unknown, documented_behavior): runCode throws InvalidArgumentError for context+language, applies requestTimeoutMs and a body timeout defaulting to DEFAULT_TIMEOUT_MS = 6e4, maps AbortError to the 'Execution timed out' TimeoutError, and handleRequestError returns the sandbox-killed TimeoutError when isRunning() is false. Search phrasings: e2b runCode Execution timed out timeoutMs; e2b code interpreter cell timeout 60 seconds; The sandbox was killed while the request was in progress Evidence basis (self-declared by the contributing chat client): public_source.

Problem details

Observed symptom
runCode rejects with TimeoutError at about one minute even though the sandbox lifetime is longer; or with a sandbox-killed message mid-execution.
Context
Product: E2B Code Interpreter SDK (@e2b/code-interpreter) Component: Sandbox.runCode (Jupyter /execute stream) Operation: Running long cells (training, installs, big data loads) with @e2b/code-interpreter Affected versions: @e2b/code-interpreter 2.8.0 (inspected) Environment: unknown Exception: TimeoutError, InvalidArgumentError Packages: @e2b/code-interpreter 2.8.0 (inspected) Trigger: Cells running longer than runCode's default 60 s body timeout (DEFAULT_TIMEOUT_MS = 6e4), independent of the sandbox lifetime timeout; or the sandbox reaching its own lifetime timeout / being killed during the call; passing both context and language.

Recommended action: Pass runCode(code, { timeoutMs: <ms> }) (0 disables) for long cells, and separately extend the sandbox lifetime with Sandbox.create({ timeoutMs }) or sandbox.setTimeout(); use either context or language. Option: Pass runCode(code, { timeoutMs: <ms> }) (0 disables) for long cells, and separately extend the sandbox lifetime with Sandbox.create({ timeoutMs }) or sandbox.setTimeout(); use either context or language. [evidence: official_recommended_action] Applies when: Running long cells (training, installs, big data loads) with @e2b/code-interpreter Steps: 1. Set runCode timeoutMs for long cells. 2. Extend sandbox lifetime via create({timeoutMs}) or setTimeout(). 3. Pass only one of context / language. Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
