failed to get flow search log: %w

Error message

failed to get flow search log: %w

What it means

Wraps a failure from cnts.slc.GetFlowSearchLog(ctx, flowID) while building flowProviderWorkers; the search-log stream for the flow could not be retrieved. The original error is preserved via %w. Like the sibling log fetchers, any single failure aborts the entire flow log assembly.

Solutions

1. Inspect the wrapped error for the storage-level cause (connection, timeout, not-found).
2. Verify the flowID is valid in the current database.
3. Run pending goose migrations so search-log tables exist.
4. Retry on transient DB errors; check connection-pool settings.

var exists bool
err := db.QueryRow("SELECT EXISTS(SELECT 1 FROM flows WHERE id=$1)", flowID).Scan(&exists)
if err != nil || !exists { /* abort with 404 */ }

func isSearchLogError(err error) bool {
	return err != nil && strings.Contains(err.Error(), "failed to get flow search log")
}

slw, err := cnts.slc.GetFlowSearchLog(ctx, flowID)
if err != nil {
	if isTransient(err) { /* retry with backoff */ }
	return nil, fmt.Errorf("failed to get flow search log: %w", err)
}

When it happens

Trigger: Flow detail/log retrieval call where the search-log component's storage query for flowID fails or returns an unexpected error.

Common situations: Search-log table missing from failed migrations; DB connection dropped mid-request; flowID referencing a nonexistent or purged flow.
