I've tried to create an upstream branch using "git webkit pr" that added hundreds of new pixel test results. However automatic PR creation failed: $ git webkit pr ... * [new branch] eng/macOS-Check-in-remaining-pixel-test-results-to-assist-LBSE-development -> eng/macOS-Check-in-remaining-pixel-test-results-to-assist-LBSE-development Total 0 (delta 0), reused 0 (delta 0), pack-reused 0 To github.com:nikolaszimmermann/WebKit.git 027340c60ceb..747aaf24c4e9 main -> main Validation failed when creating pull request Does a pull request against this branch already exist? Failed to create pull-request for 'eng/macOS-Check-in-remaining-pixel-test-results-to-assist-LBSE-development' ... The real issues was that the body of the GitHUB pr exceeded 65536 characters. git webkit pr should be able to shorten on its own, to avoid that issue.
