Resolved 💬 21 comments Opened Jan 7, 2026 by marcondesmacaneiro Closed Apr 8, 2026

Bug Description

When attempting to resume a previous session using the interactive picker or --resume flag, Claude Code crashes with the following error:

ERROR  Cannot read properties of undefined (reading 'trim')

Steps to Reproduce

Have existing sessions in Claude Code history
Run claude and use the interactive picker to select a previous session to resume
Or run claude --resume and select a session
Error occurs immediately when trying to resume

Environment

Claude Code Version: 2.1.1 (also occurred on 2.0.76)
Node.js Version: v22.17.0
OS: macOS (Darwin 25.1.0)
Shell: zsh

Investigation Done

Session file (.jsonl) is valid JSON - no corrupted lines
All summary entries in the session file have valid string content (not null or empty)
The issue persists even after upgrading from 2.0.76 to 2.1.1

Expected Behavior

Session should resume normally without crashing.

Additional Context

The session being resumed had 73 messages and the .jsonl file is ~927KB. The file passes JSON validation for all lines.

Got same problem.
I ma using docker container with:
OS: debian:bookworm
Shell: bash
Claude code version: node2.0.76 (Claude Code)
nodejs version: v22.21.0

MikeGitIt · 5 months ago

SAME PROBLEM, using the npm client, not the "native" one. If you all are using Claude Code, to develop Claude Code, then you all are not proving the greatness of Claude Code. Just sayin.

ivan2kh · 5 months ago

Same on 2.1.22.

---

## Environment

Claude Code: 2.1.22
Node.js: v22.21.0
OS: Linux 6.8.0-90-generic x86_64

## Description
When trying to resume a session that was interrupted (Ctrl+C), Claude Code crashes with a trim() error on undefined.

## Steps to reproduce

Start a Claude Code session
Interrupt it with Ctrl+C
Try to resume with claude --continue
Crash occurs

## Reproducibility
Always - happens every time when trying to resume an interrupted session.

## Error
```
ERROR Cannot read properties of undefined (reading 'trim')

hA (file:///usr/lib/node_modules/@anthropic-ai/claude-code/cli.js:601:7651)

```

## Expected behavior
Session should resume successfully, or provide a clear error message if the session data is corrupted.

## Workaround
Deleting session files in ~/.claude/projects/*/sessions/ allows starting fresh.

Likely same root cause as #27219 — the TUI renderer calls .trim() on an undefined field when replaying hook event records (hook_success, hook_blocking_error, etc.) during --resume. Root cause analysis and stack trace from the Bun bundle there.

Hi, @huahanqi @xhrg . I have the same issue in vscode.

Bug detail in Webview Developer Tool's console

TypeError: Cannot read properties of undefined (reading 'trim')

````

## Workaround (local patch):
**If you have the same bug detail**, you can walkround by:

Find lB1 in your extension's webview/index.js:

~/.vscode/extensions/anthropic.claude-code-<version>-<platform>/webview/index.js


Replace (line 1439 in my file):

function lB1($){return!$.text.trim()||$.text.trim()===cB1}

With:

function lB1($){return!($.text||"").trim()||($.text||"").trim()===cB1}


## Root cause

lB1 calls `$.text.trim()` without checking if `$.text exists`, causing the crash.

Hope this helps

silunuo · 4 months ago

face a similar :
Error rendering content: Cannot read properties of undefined (reading 'trim')

Steps: When total project context (multiple sessions) is too long, sending a new request triggers the error (not when resuming a session).
Env: Claude Code (npm)lastest, Windows11

On macos, claude code version: anthropic.claude-code-2.1.76-darwin-arm64

the function's name is different, it's called: aB1

Find aB1 in your extension's webview/index.js:

~/.vscode/extensions/anthropic.claude-code-<version>-<platform>/webview/index.js

Replace (line 1439 in my file):

function aB1($){return!$.text.trim()||$.text.trim()===sB1}

With:

function aB1($){return!($.text||"").trim()||($.text||"").trim()===sB1}

The minified function names may differ across platforms due to differences in the build environment or AST transformations.

In practice, you can fix this issue by replacing $.text.trim() with ($.text || "").trim() at the corresponding error line (usually line 1439) in:
~/.vscode/extensions/anthropic.claude-code-<version>-<platform>/webview/index.js

Yes, there are platform differences — I noticed this when applying the fix. On Windows (anthropic.claude-code-2.1.79-win32-x64), it's eB1 / tB1 in my index.js, not lB1 / cB1 or aB1 / sB1 as mentioned above. Everything else is the same.
