Google Drive API call to insert Public Share permissions on Fusiontables causes Internal Error

Question

I have been trying to use the Google Drive API to make a Fusiontable publicly readable, and have not been able to get it to work. I am able to use the OAuth 2.0 Playground to insert public share permissions for other Google Drive documents, but for Fusiontables I get an HTTP 500 error, "Internal Error". Note that I have tried including every scope available under "Drive API v2" and "Fusion Tables API v1".

I'm aware that Google is no longer developing and supporting Fusiontables, but I'm wondering if anyone has found a workaround that allows them to get around this problem? I haven't tried legacy/deprecated versions of the API either.

Here's are the actual API request format and responses from OAuth Playground for a Fusiontable permissions insert (HTTP 500), then a Doc permissions insert (HTTP 200). The only difference between requests is the fusiontable_id or document_id in the Request URI:

Request:

POST /drive/v2/files/<fusiontable_id or document_id>/permissions HTTP/1.1
Host: www.googleapis.com
Content-length: 33
Content-type: application/json
Authorization: Bearer <access_token>

{"role":"reader","type":"anyone"}

Fusiontable Response:

      }
    ]
  }
}

This appears to be due to a bug in the Drive API. I've located the internal error and have raised the issue with the engineering team. At this time there are no known workarounds.
