🤖 Generated with Claude Code

The previous instance was closed and none of the details there helped address this issue. My claude.md is quite small.

I've been having this problem too, and it's been going on for 30 minutes now that I've noticed

I downgraded to 2.1.77 and the problem went away. Used the command: curl -fsSL https://claude.ai/install.sh | bash -s 2.1.77. Also, note that it install in the /local path unless you actively uninstall the current version. So, the next time you run "claude" cli run it from the /bin/ path that it downloaded 2.1.77 to.

Thanks, the issue was fixed after rolling back to the previous version

Confirmed. Upgrading Node.js from v18 to v20 fixed the issue for me.

Root cause: Array.prototype.with() was introduced in Node v20. Claude Code v2.1.78 uses this API, which causes a silent crash on Node v18, manifesting as repeated "Interrupted · What should Claude do instead?" with no error message.

Fix:

nvm install 20 && nvm use 20
npm install -g @anthropic-ai/claude-code

After upgrading, /compact no longer throws TypeError: A.with is not a function and sessions run normally.

我的也是一样，降级到上一个版本就没有此问题了。

Detailed technical analysis from CI/headless mode debugging

We hit this same regression in our headless CI pipeline (claude -p in GitHub Actions with AWS Bedrock). Here's what we found after ~10 diagnostic CI runs.

Root cause: Node.js v18 incompatibility

Claude Code v2.1.78 uses Array.prototype.with(), which was introduced in Node.js v20. On Node.js v18, this causes a silent crash that manifests as [Request interrupted by user] / error_during_execution.

Fix: upgrade Node.js from v18 to v20. After upgrading, Claude Code v2.1.78 (latest) works correctly — verified in CI with a full successful run (42 turns, ~3.5 min).

How we found it

The --debug-file output showed this warning before the interruption:

[WARN] auto mode disabled: tengu_auto_mode_config.enabled === "disabled" (circuit breaker)

This turned out to be a downstream symptom of the Array.prototype.with() crash — the internal state gets corrupted, triggering the circuit breaker, which then fires the abort controller and injects [Request interrupted by user] into the conversation.

Symptom sequence (from --output-format stream-json)

1. Claude completes 9-16 turns successfully (tool calls work fine)
2. The tengu_auto_mode_config circuit breaker fires (due to underlying A.with is not a function error)
3. The abort controller signals with reason "interrupt"
4. A [Request interrupted by user] text message is injected into the conversation
5. The internal validation function fails (expects tool_result blocks, finds text)
6. Returns error_during_execution with an empty errors array

Version timeline

| Date | Version | Node.js | Result |
|------|---------|---------|--------|
| March 17, ~09:00 UTC | 2.1.77 | v18 | SUCCESS |
| March 18, ~09:00 UTC | 2.1.78 | v18 | FAILURE |
| March 18 (test 1) | 2.1.77 pinned | v18 | SUCCESS |
| March 18 (test 2) | 2.1.78 (latest) | v20 | SUCCESS |

What we ruled out

• Not a permissions issue (--dangerously-skip-permissions didn't help)
• Not a turn limit (--max-turns 200 didn't help)
• Not a stdin issue (< /dev/null didn't help)
• Not API connectivity (9-16 successful API calls before interrupt)

Environment

• GitHub Actions runner (Ubuntu)
• AWS Bedrock (CLAUDE_CODE_USE_BEDROCK=1)
• Models: us.anthropic.claude-sonnet-4-5-20250929-v1:0, us.anthropic.claude-haiku-4-5-20251001-v1:0

Fix

Upgrade Node.js to v20+:

- uses: actions/setup-node@v3
  with:
    node-version: '20'  # Required for Array.prototype.with() used by Claude Code v2.1.78+

This solution solved our issue. Thank you.

Same issue here. Version 2.1.79, macOS (darwin), Node v18.20.8. Claude auto-interrupts every tool use (Search, Read, Bash) with "Interrupted · What should Claude do instead?" without any user input. Happens in both VS Code integrated terminal and external Terminal.app. Reinstalling did not fix it. Session never completes any task, just loops and ends with "Worked for Xs".

https://github.com/anthropics/claude-code/issues/35643#issuecomment-4080873697 worked for me, too. Thanks.

Reinstalling claude using the new native installer (curl -fsSL https://claude.ai/install.sh | bash) seems to have fixed this for me.

This was fixed in v2.1.81 — Sessions on Node 18 (npm install) no longer self-interrupt with a TypeError on the first progress update. If you're still seeing this in the latest version, please comment with your version and repro and we'll reopen.
