python sometimes throws error while sending private message with 'send_msg_with_retry'

[do6uk]

sending private messages with 'send_msg_with_retry' sometimes failes with following exception ...

File "/home/rainer/.local/lib/python3.13/site-packages/meshcore/commands/messaging.py", line 150, in send_msg_with_retry
exp_ack = result.payload["expected_ack"].hex()
~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^
KeyError: 'expected_ack'

it is not clear what caused the error. same message at same contact mostly works - sometimes didn't

Thanks for reporting this I've not been able to reproduce yet. If it happens enough could you please give me the content of `result.payload` when this happens ? An eventual error should be caught, I would like to know what has been returned if it's neither a correct payload nor an error ...
