Public bug reported:

API fails during live migration with a 500 internal server error.

https://127.0.0.1:8774/v2/8c87f173ba7c47cbb4f57eebe85479c1/servers/d53b954a-7323-4d88-a5fc-14c0672a704e/action
{
    "os-migrateLive": {
        "host": "8231E2D_109EFCT",
        "block_migration": false,
        "disk_over_commit": false
    }
}

The correct error should be 400 BadRequest as the error raise should be
RemoteError, not a MigrationError

Nova-api logs:
