copy comment for %s: %w

Error message

copy comment for %s: %w

What it means

Comments are copied with dst.ImportIssueComment (preserving original author and created_at). If that write fails, migration aborts with this error for the issue.

Solutions

1. Check the wrapped inner error to find the failing write cause.
2. Close competing bd processes and retry the migration.
3. Validate comment rows in the source (non-empty author/timestamp) before migrating; repair the source if a row is malformed.

// validate comment payloads before import
for _, c := range comments {
    if c.CreatedAt.IsZero() || c.Author == "" {
        return fmt.Errorf("comment for %s has invalid author/timestamp", issue.ID)
    }
}

When it happens

Trigger: dst.ImportIssueComment(ctx, issue.ID, c.Author, c.Text, c.CreatedAt) errors — destination driver write failure, DB lock, or invalid comment payload (e.g. nil/zero CreatedAt rejected by the driver).

Common situations: Destination DB locked by another bd session, or a comment with malformed author/timestamp data tripping a driver constraint.
