claude-code - 💡(How to fix) Fix [BUG] Preview tool screenshot always returns black image after browser gets into broken state [1 participants]

chrome-error://chromewebdata/ — the internal browser gets stuck on this URL and cannot navigate to localhost.

TL;DR

The internal browser getting stuck on chrome-error://chromewebdata/ likely causes the screenshot issue, and resolving this navigation problem may fix the screenshot capture.

Guidance

• Verify that the internal browser can navigate to localhost without getting stuck on chrome-error://chromewebdata/ by checking the browser's navigation behavior outside of the screenshot capture process.
• Check if there are any browser extensions or settings that could be interfering with the internal browser's navigation.
• Attempt to reproduce the issue with a different Claude model or version to isolate if the problem is specific to the Sonnet model or version 4.6.
• Consider resetting the internal browser's settings or clearing its cache to see if this resolves the navigation issue.

Example

No specific code snippet is provided as the issue seems related to the internal browser's behavior rather than a code-specific problem.

Notes

The issue seems to be related to the internal browser's ability to navigate to localhost, and resolving this may require further investigation into the browser's settings or the environment in which it is running. The fact that this is a regression suggests that a change in the Claude Code version or the environment may have introduced this issue.

Recommendation

Apply workaround: Given the information, a workaround such as resetting the internal browser or checking for interfering extensions might be necessary until the root cause is identified and fixed.
