hydrate ready row %s: comment counts: %w
Error message
hydrate ready row %s: comment counts: %w
What it means
hydrateReadyRow fetches comment counts for the claimed issue via CommentUseCase().GetCommentCounts and wraps any failure. This is the third hydration step (after dependency counts and records); failing here aborts the claim so a partially hydrated result is never returned to the caller.

// hydrateReadyRow fills in the relationship cardinalities a ready row carries,
// reading them in the caller's unit of work so the counts describe the state
// that transaction is about to commit. A failed count read is an error rather
// than a zero, matching the store-backed sibling: a result nobody can hydrate
// is not a result.

Solutions
- Retry the claim/ready command
- Inspect the wrapped underlying error (%w) via server logs or verbose output
- Check grants on the comments table
- Increase timeouts if comment count queries are slow
Example fix
null
Defensive patterns
Strategy: retry
Validate before calling
// Go: pre-verify comment counts are computable
_, err := uw.CommentUseCase().GetCommentCounts(ctx, []string{issueID})
if err != nil { /* resolve access/perf issues before claiming */ } Type guard
func isCommentCountHydrationError(err error) bool {
return err != nil && strings.Contains(err.Error(), "comment counts: ")
} Try / catch
issue, err := ClaimNextInUOW(ctx)
if isCommentCountHydrationError(err) {
// transient: back off and retry once before surfacing
time.Sleep(time.Second); issue, err = ClaimNextInUOW(ctx)
}
return issue, err Prevention
- Grant the bd SQL user access to comment tables
- Index/maintain comment tables so COUNT queries stay fast on large DBs
- Set generous timeouts for count queries under load
- Retry transient errors; escalate persistent ones with the %w chain
When it happens
Trigger: ClaimNextInUOW → hydrateReadyRow where GetCommentCounts(ctx, [issueID]) errors — SQL failure, connection loss, or comment use-case error while counting comments for the claimed issue.
Common situations: Dolt server error during 'bd ready'; permission problems on comment tables; large comment tables making the count query time out; transient network interruption.
