error storing plan config: %v

Error message

error storing plan config: %v

What it means

StorePlanConfig wraps a failure of `UPDATE plans SET plan_config = $1 WHERE id = $2` with this message. Note the UPDATE silently affects zero rows when planId doesn't exist — this wrap only fires on actual Exec errors: connection failure, driver serialization error for the config, or schema problems.

Solutions

1. Inspect the wrapped cause for connection vs encoding errors; for connection errors check Postgres health and retry
2. Confirm migrations have created plans.plan_config with the expected type (JSONB/text)
3. Validate the incoming PlanConfig payload (JSON-serializable, size limits) before storing
4. After a successful Exec, also check RowsAffected if you need to detect a nonexistent planId, since zero rows is not an error here

Example fix

// before
err := StorePlanConfig(planId, config)
// after: detect zero-row updates too
res, err := Conn.Exec("UPDATE plans SET plan_config = $1 WHERE id = $2", config, planId)
if err != nil { return err }
n, _ := res.RowsAffected()
if n == 0 { return fmt.Errorf("plan %s not found", planId) }

// validate payload and target row before the UPDATE
b, err := json.Marshal(config)
if err != nil {
    return fmt.Errorf("invalid plan config: %w", err)
}
var exists bool
Conn.Get(&exists, "SELECT EXISTS(SELECT 1 FROM plans WHERE id=$1)", planId)

err := StorePlanConfig(planId, config)
if err != nil {
    log.Printf("StorePlanConfig(%s): %v", planId, err) // inspect cause
    http.Error(w, "failed to save config", http.StatusInternalServerError)
    return
}

When it happens

Trigger: UpdatePlanConfigHandler calls StorePlanConfig and Conn.Exec fails: DB unreachable, plans table/column missing (migration drift), or the *shared.PlanConfig value cannot be encoded by the driver into plan_config.

Common situations: Postgres restart or connection-pool exhaustion during a config save; running against a database without the plan_config column; a PlanConfig containing unsupported field types the lib/pq encoder rejects; concurrent migration changing the schema.
