+## Input
+
+```javascript
+import idx from 'idx';
+
+function Component(props) {
+  // the lambda should not be outlined
+  const groupName = idx(props, _ => _.group.label);
+  return <div>{groupName}</div>;
+}
+
+export const FIXTURE_ENTRYPOINT = {
+  fn: Component,
+  params: [{}],
+};
+
+```
+
+
+## Error
+
+```
+The second argument supplied to `idx` must be an arrow function. (This is an error on an internal node. Probably an internal error.)
