Unexpected error occured when creating a PR in v0

[changyongkang1001-66 (ck)]

When I commit and push the new version into dev branch in local development, the current branch pull-from-dev (created a branch from dev by v0) is behind the base branch. So when I try to sync by making a PR, it shows an unexpected error occured.

Can someone tell me what is the issue?

Updated:
After I manually create PR from github and come back to v0, when I click on “Pull Changes“, it shows the same error

The current solution is restart the v0 sandbox, then click again the “Open Pull Request“ or “Pull Changes“ and it works
