[SharingNg] user with role Uploader trying to reshare a resource returns 500 status code

[PrajwolAmatya]

Describe the bug

When a resource is shared with a user with Uploader role, and that user tries to reshare it with other users, it is supposed to fail with proper status code and message as user with role Uploader cannot reshare resource, but it is currently returning status code 500.
Also, user with roles like Viewer tries to reshare resouce to other users with higher roles like Editor, or Manager, it also returns 500 status code.

Steps to reproduce

1. User Alice creates a folder FolderToShare
2. Alice shares the folder with user Brian with role Uploader using SharingNg

curl -kv -XPOST "https://localhost:9200/graph/v1beta1/drives/{drive-id}/items/{item-id}/invite" -d '{
  "recipients": [
    {
      "@libre.graph.recipient.type": "user",
      "objectId": "4c510ada-c86b-4815-8820-42cdf82c3d51"
    }
  ],
  "roles": [
    "1c996275-f1c9-4e71-abdf-a42f6495e960"
  ]
}' -uAlice:1234 | jq

3. Brian tries to reshare folder FolderToShare to user Carol with Viewer role

curl -kv -XPOST "https://localhost:9200/graph/v1beta1/drives/{drive-id}/items/{item-id}/invite" -d '{
  "recipients": [
    {
      "@libre.graph.recipient.type": "user",
      "objectId": "534bb038-6f9d-4093-946f-133be61fa4e7"
    }
  ],
  "roles": [
    "b1e2218d-eef8-4d4c-b82d-0f1a1b48f3b5"
  ]
}' -uBrian:1234 | jq

Actual behavior

The share fails with status code 500.
