## Steps to reproduce

Steps to reproduce the behavior:

1. Create a user `Alice`
2. Create a group `Demo`
3. Try adding user `Alice` to group `Demo` using the API request with invalid host in `@odata.id`

```
curl -k --header "Content-Type: application/json" \
--request POST --data \
'{ "@odata.id": "https:///graph/v1.0/users/" }' \
'https://localhost:9200/graph/v1.0/groups//members/$ref' -u admin:admin
```

The user should not be added to the group.

## Actual behavior
The user is added to the group and the response status code is `204`.
