claude-code - 💡(How to fix) Fix [Bug] Code generation produces broken output

[{"error":"Error: NON-FATAL: Lock acquisition failed for /Users/aeufemio/.local/share/claude/versions/2.1.114 (expected in multi-process scenarios)\n at sd_ (/$bunfs/root/src/entrypoints/cli.js:2751:2177)\n at WH8 (/$bunfs/root/src/entrypoints/cli.js:2751:1257)\n at processTicksAndRejections (native:7:39)","timestamp":"2026-04-20T20:41:18.824Z"}]

TL;DR

The issue may be resolved by ensuring proper lock acquisition for the /Users/aeufemio/.local/share/claude/versions/2.1.114 directory, potentially by running the command in a single-process scenario or checking for existing lock files.

Guidance

• The error message suggests a lock acquisition failure, which may be due to multiple processes trying to access the same resource simultaneously.
• Check the directory /Users/aeufemio/.local/share/claude/versions/2.1.114 for any existing lock files or processes that may be holding onto the lock.
• Try running the command in a single-process scenario to see if the issue persists.
• Verify that the user running the command has proper permissions to access and modify the directory.

Notes

The provided error message is quite specific, but without more context about the command being run or the environment, it's difficult to provide a more detailed solution. The issue may be related to the specific version of the software being used (2.1.114) or the platform (darwin).

Recommendation

Apply workaround: Try running the command in a single-process scenario or checking for existing lock files to resolve the lock acquisition failure.
