claude-code - 💡(How to fix) Fix SDK 2.1.111 regression: Failed to create bridge sockets after 5 attempts (Cowork broken) [2 comments, 3 participants]

TL;DR

Rolling back the SDK to version 2.1.92 is likely the most immediate fix to resolve the cowork session crashes.

Guidance

• Verify that the issue is indeed caused by the SDK update by checking the logs for any other potential errors or warnings that may have occurred around the same time as the update.
• Attempt to roll back the SDK to version 2.1.92 to confirm if this resolves the issue, as the logs suggest that this version was working correctly before the update.
• If rolling back is not feasible, investigate potential configuration changes or environment updates that may have been introduced with the SDK update to version 2.1.111 that could be causing the bridge socket error.
• Consider reaching out to the SDK developers or support team for further assistance, as the error message "Failed to create bridge sockets after 5 attempts" may indicate a bug or compatibility issue with the new version.

Example

No specific code snippet can be provided without more context, but the log evidence suggests that the issue is related to the SDK version update.

Notes

The exact cause of the issue is not certain, but the correlation between the SDK update and the start of the errors suggests a strong link. Rolling back to a known working version (2.1.92) is a reasonable first step to mitigate the issue while further investigation is conducted.

Recommendation

Apply workaround: Roll back the SDK to version 2.1.92, as this version was confirmed to be working before the update, and the error started immediately after the update to 2.1.111.
