Macos failed to execute mnist oneline example

Trying to run `python/examples/simulation/sp_fedavg_mnist_lr_example/torch_fedavg_mnist_lr_one_line_example.py`. It loops forever in `server_runner.py:bind_account_and_device_id`.
Because the request to `https://open.fedml.ai/fedmlOpsServer/edges/binding` in `client_runner.py:bind_account_and_device_id` keeps responding a `DATA_NO_EXIST_ERROR` status_code.
Here is the request json to `https://open.fedml.ai/fedmlOpsServer/edges/binding` (personal information asterisked).
