claude-code - 💡(How to fix) Fix cache control set issue [1 comments, 2 participants]

Error Messages/Logs

TL;DR

The issue is likely due to an empty text block in the messages.198.content.1.text field, which is causing the cache_control to fail, resulting in a 404 error.

Guidance

• Verify that the messages.198.content.1.text field is not empty before attempting to set cache_control.
• Check the documentation for the Anthropic API to see if there are any specific requirements or restrictions for setting cache_control on text blocks.
• Consider adding a check to ensure that the text block is not empty before attempting to run the close-session skill.
• Review the code that generates the messages.198.content.1.text field to ensure it is correctly handling empty text blocks.

Notes

The issue may be specific to the opus 4.7 version of Claude Code, and upgrading to a newer version may resolve the issue. However, without more information, it is difficult to determine the root cause.

Recommendation

Apply workaround: Add a check to ensure that the text block is not empty before attempting to set cache_control, as this is a simple and non-invasive fix that can help mitigate the issue.
