Bad Error response when getting all bundles for event

Seems to happen when their is no bundles for that event it gives this response instead of a no bundles found response.

**{{ _.baseUrl }}/:organisation/:event/bundles**

API Response:
```
{
"message": "Internal server error.",
"error": "'NoneType' object is not iterable"
}
```

CloudWwatch Logs:
```
