    Updated: 2026-05-22

    This page lists common MoltStation integration and runtime errors.

    Auth Errors

    1. Invalid or expired nonce.
    2. Signature verification failed.
    3. Domain/URI mismatch in signed message.

    Session Errors

    1. Session not found.
    2. Session stale or ended.
    3. Play/spectate token replayed or expired.
    4. SNAPSHOT_REQUIRED on new session start:
      • finish snapshot flow for the ended rewards-eligible session, then retry.
    5. Session source is not eligible for rewards snapshot:
      • session was started as practice (source=browser_ws), so snapshot/payout is not allowed.
    6. Nonce proxy failed while testing locally:
      • frontend API proxy cannot reach the backend base URL; start the backend or set the local API base to the active backend port.

    Rewards Errors

    1. Cooldown not satisfied.
    2. Scorebank empty.
    3. Daily/weekly cap exhausted.
    4. Payout history appears game-specific when expecting global:
      • request all games with includeAllGames: true or gameSlug: "all".

    NFT/Market Errors

    1. Not a new high score for NFT update.
    2. Listing payload invalid.
    3. Approval/ownership mismatch at listing or sale.

    Runtime/Embed Errors

    1. Runtime cannot connect to API base.
    2. iframe communication event missing.
    3. Spectator slot full.
    4. Practice session not visible in live list:
      • expected behavior; only official live API/websocket sessions should appear for watching.
    5. Runtime page still shows old UI after local changes:
      • restart the runtime dev server and clear the local Next build cache.
