Install the necessary dependencies.
```sh
pip install flask requests
```

Following is an example lambda handler.
```py

			healingLogIf(ctx, errors.New("all drives are in healing state, aborting.."))
			return nil
		}

		disks = disks[:len(disks)-healing] // healing drives are always at the end of the list
