+### `No loader is configured for ".node" files`
+
+This happens because `.node` files are native code and can't be bundled like other packages. To fix this, add your package to [`build.external`](/config/config-file#external) in the `trigger.config.ts` file like this:
+
+```ts trigger.config.ts
+import { defineConfig } from "@trigger.dev/sdk/v3";
+
+export default defineConfig({
+  project: "<project ref>",
+  // Your other config settings...
+  build: {
+    external: ["your-node-package"],
+  },
+});
+```
