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

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.

Proposed fix: [E2B Code Interpreter JS] sandbox.runCode(): TimeoutError 'Execution timed out — the 'timeoutMs' option can be used to increase this timeout' after 60 s, or 'The sandbox was killed while
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.
