issue token with project-scope get error: "object of type 'NoneType' has no len()"

[Bi wei]

/v3/auth/tokens POST method for "Password authentication with scoped authorization".

When sets project-scoped with project ID key but the value is a domain id as following:
{
    "auth": {
        "identity": {
            "methods": [
                "password"
            ],
            "password": {
                "user": {
                    "id": "a83947b5fc594f3ca92f1f2f254f6459",
                    "password": "devstack"
                }
            }
        },
        "scope": {
            "project": {
                "id": "default"
            }
        }
    }
}

It returns:
{
    "error": {
        "message": "object of type 'NoneType' has no len()",
        "code": 400,
        "title": "Bad Request"
    }
}

This message is unreadable for users.

I think it should raise 404 project not found internal but 401 to end user.
