42900 — rate_limited

Back off, then retry. Not terminal.

At a glance — HTTP 429 · terminal: no · SDK FluxyRateLimitError.

What to do

• Wait the server's hint — REST responses carry retryAfter, or the Retry-After header — then retry.
• In the SDK, catch FluxyRateLimitError and wait retryAfterMs before the next call.
• Batch or throttle bulk sends instead of retrying in a tight loop.

import { FluxyRateLimitError } from "@fluxy-chat/sdk";

try {
  await sendBatch();
} catch (err) {
  if (err instanceof FluxyRateLimitError) {
    await new Promise((resolve) => setTimeout(resolve, err.retryAfterMs));
    // retry once, or hand the delay back to your queue
  }
}
