+This page documents error codes returned by Queues when using the [Workers API](/r2/api/workers/).
+
+## How errors are returned
+
+For the [JavaScript APIs](/queues/configuration/javascript-apis/), Queues operations throw exceptions that you can catch. The error code is included at the end of the `message` property:
+
+```js
+try {
+	await env.MY_QUEUE.send("message," { delaySeconds: 999999});
+    return new Response('Sent message to the queue');
+} catch (error) {
+	console.error(error);
+	return new Response('Failed to send messag to the queue`, { status: 500});
+}
+```
+
+For the [Cloudflare API via HTTP](/api/resources/queues/subresources/messages/), the response will include an `errors` object which has both a `message` and `code` field:
+
+```
+{
+  "errors": [
+    {
+      "code": 7003,
+      "message": "No route for the URI",
+      "documentation_url": "documentation_url",
+      "source": {
+        "pointer": "pointer"
+      }
+    }
+  ],
+  "messages": [
+    "string"
+  ],
+  "success": true
+}
+```
