What's Wrong?

When I create a PR via GH CLI, randomly, the application will fail with error code

 API Error: 413 {"error":{"type":"request_too_large","message":"Request exceeds the maximum size"}}

No other messages will succeed after that:

Create the PR

⎿  API Error: 413 {"error":{"type":"request_too_large","message":"Request exceeds the maximum size"}}

Why are you throwing an error 413?

⎿  API Error: 413 {"error":{"type":"request_too_large","message":"Request exceeds the maximum size"}}

● Background command "Commit nova template migration" failed with exit code 137.
⎿  API Error: 413 {"error":{"type":"request_too_large","message":"Request exceeds the maximum size"}}

What Should Happen?

Claude should create the PR or indicate an error. Claude should also allow a next command to execute.

Steps to Reproduce

1. Occurs randomly. I cannot define a pattern.

Bash(git add .)
Bash(git commit -m "feat:.....)
Bash(git push -u origin feature/branch-name)
Bash(gh pr create --title "feat:...." --body "## Summary...) <this command fails>

1. Get API Error: 413.
