Failed to subscribe to triggers: ${errorMessage}

Error message

Failed to subscribe to triggers: ${errorMessage}

What it means

Catch-all wrapper around any failure in triggerSubscribe (init guard, subscription error, bind setup). The underlying message is appended, so inspect it to distinguish errors 404/405/403.

Solutions

1. Parse the appended underlying message to route to the right fix (init order vs auth vs chunking)
2. Ensure getPusherClient completed successfully first with valid credentials
3. If the appended text mentions 'Trigger subscription error', follow the auth troubleshooting for the API key/baseURL/clientId trio

try {
  PusherUtils.triggerSubscribe(clientId, fn);
} catch (e) {
  const msg = e instanceof Error ? e.message : String(e);
  logger.error('Trigger subscription failed:', msg);
  // route to fix based on appended cause
}

When it happens

Trigger: Any failure within PusherUtils.triggerSubscribe: client not initialized, pusher:subscription_error, or bindWithChunking throwing during setup.

Common situations: Any of the underlying trigger-subscription failures bubbling through the outer try/catch; most commonly auth failures (405) or initialization order (404).
