# my.offUnhandledRejection

> Stop listening for unhandled Promise rejection events.

Use this API to stop listening for unhandled Promise rejection events that were registered with `my.onUnhandledRejection()`.

## Parameters

| Property | Type     | Required | Description                                                             |
| -------- | -------- | -------- | ----------------------------------------------------------------------- |
| callback | Function | No       | The specific callback to remove. If omitted, all listeners are removed. |

## Code Example

### Remove Specific Listener

```javascript theme={null}
App({
  onLaunch() {
    my.onUnhandledRejection(this.rejectionHandler);
  },

  rejectionHandler(res) {
    console.error('Unhandled rejection:', res.reason);
  },

  // Call this to remove the listener
  removeRejectionListener() {
    my.offUnhandledRejection(this.rejectionHandler);
  }
});
```

### Remove All Listeners

```javascript theme={null}
// Remove all unhandled rejection listeners
my.offUnhandledRejection();
```

### Page Lifecycle Management

```javascript theme={null}
Page({
  onShow() {
    my.onUnhandledRejection(this.handleRejection);
  },

  onHide() {
    // Clean up when page is hidden
    my.offUnhandledRejection(this.handleRejection);
  },

  handleRejection(res) {
    console.error('Rejection on page:', res.reason);
  }
});
```

<Tip>
  Pass the same callback function reference to `my.offUnhandledRejection()` that was used with `my.onUnhandledRejection()` to remove only that specific listener.
