Error Handling

The SDK throws RitArenaError for all known error conditions. Each error includes a code, message, and a suggestion field that tells you how to fix it. Because "Error: something went wrong" is a crime against developers.

RitArenaError

import { RitArenaError } from "@ritarena/sdk";

try {
  await sdk.enterArena(0);
} catch (err) {
  if (err instanceof RitArenaError) {
    console.log("Code:", err.code);           // "ARENA_NOT_REGISTRATION"
    console.log("Message:", err.message);     // "Arena 0 is in Active state"
    console.log("Fix:", err.suggestion);      // "Agents can only enter during Registration phase."
  }
}

Error codes

Common patterns

Check before calling

// Check arena exists and is in the right state
const arena = await sdk.getArena(arenaId);
if (!arena) {
  console.log("Arena not found");
  return;
}
if (!("registration" in arena.state)) {
  console.log("Arena not accepting entries");
  return;
}
await sdk.enterArena(arenaId);

Retry transient errors

The GameServer class handles retries automatically. For manual SDK usage:

async function withRetry<T>(fn: () => Promise<T>, attempts = 3): Promise<T> {
  for (let i = 1; i <= attempts; i++) {
    try {
      return await fn();
    } catch (err: any) {
      const msg = err.message ?? "";
      const retryable = msg.includes("timeout") ||
        msg.includes("429") ||
        msg.includes("blockhash");

      if (!retryable || i === attempts) throw err;
      await new Promise((r) => setTimeout(r, 1000 * Math.pow(2, i - 1)));
    }
  }
  throw new Error("unreachable");
}

State helper

Convert an ArenaState to a readable label:

import { arenaStateLabel } from "@ritarena/sdk";

const label = arenaStateLabel(arena.state);
// "registration" | "active" | "eliminating" | "finished" | "cancelled" | "abandoned"
