Error getting default plan config

Error message

Error getting default plan config

What it means

GetDefaultPlanConfigHandler returns HTTP 500 when db.GetDefaultPlanConfig(auth.User.Id) errors. It fetches the user's default plan settings; failures are DB-side (query, scan, or connectivity) since only the authenticated user's ID is used.

Solutions

1. Check server logs for "Error getting default plan config: <err>" to see the cause
2. Run pending migrations so the default-config table matches the model
3. Treat missing rows as an empty default config instead of an error (sql.ErrNoRows handling)
4. Repair or reset corrupt default-config rows for the affected user

Example fix

// before
config, err := db.GetDefaultPlanConfig(auth.User.Id)
if err != nil {
    http.Error(w, "Error getting default plan config", http.StatusInternalServerError)
    return
}
// after
config, err := db.GetDefaultPlanConfig(auth.User.Id)
if errors.Is(err, sql.ErrNoRows) {
    config = shared.DefaultPlanConfig()
} else if err != nil {
    http.Error(w, "Error getting default plan config", http.StatusInternalServerError)
    return
}

// client: ensure user is authenticated first
if (!authToken) return;
const res = await fetch(base + '/plans/default-config', { headers: { Authorization: 'Bearer ' + authToken } });
if (res.status === 500) console.error('default config lookup failed; check server DB logs');

try {
  const cfg = await getDefaultPlanConfig();
} catch (e) {
  if (e.status === 500) { /* fall back to client defaults and report server issue */ }
  else throw e;
}

When it happens

Trigger: GET default plan config when the user_settings/default-config row for auth.User.Id cannot be read, the DB is unreachable, or the stored default config fails to scan/deserialize (e.g. corrupt JSON).

Common situations: Brand-new user with no row and the query not treating missing-row as empty, schema drift after upgrade, manually edited default config containing invalid JSON, transient Postgres outages.
