Backport #28334 by @lng2020 Fix #28328 ``` func (p *PullRequestComment) GetDiffHunk() string { if p == nil || p.DiffHunk == nil { return "" } return *p.DiffHunk } ``` This function in the package `go-github` may return an empty diff. When it's empty, the following code will panic because it access `ss[1]`tags/v1.21.2ec1feedbf5/services/migrations/gitea_uploader.go (L861-L867)
