claude-code - 💡(How to fix) Fix [Feature Request] Add built-in git graph visualization for branch context [1 participants]

[{"error":"RangeError [ERR_CHILD_PROCESS_STDIO_MAXBUFFER]: stdout maxBuffer length exceeded\n at Socket.onChildStdout (node:child_process:481:14)\n at Socket.emit (node:events:518:28)\n at addChunk (node:internal/streams/readable:561:12)\n at readableAddChunkPushByteMode (node:internal/streams/readable:512:3)\n at Readable.push (node:internal/streams/readable:392:5)\n at Pipe.onStreamRead (node:internal/stream_base_commons:189:23)","timestamp":"2026-04-15T01:31:15.216Z"}]

TL;DR

The issue is likely related to the stdout maxBuffer length being exceeded, and increasing this limit may help mitigate the problem.

Guidance

• The error message indicates a RangeError due to the stdout maxBuffer length being exceeded, suggesting that the output from a child process is too large.
• To verify this, check the output of the child process to see if it is indeed producing a large amount of data.
• Consider increasing the maxBuffer limit or implementing a more efficient way to handle the output from the child process.
• The fact that this issue occurs in the context of a git graph visualization suggests that the visualization tool may be producing a large amount of output.

Example

No code snippet is provided as the issue does not contain enough information to create a specific example.

Notes

The provided error message is related to a Node.js child process, but the issue description mentions a git graph visualization, which may not be directly related to the error. More information is needed to provide a definitive solution.

Recommendation

Apply workaround: Increase the maxBuffer limit to allow for larger output from the child process, as this may help mitigate the issue.
