since a recent version of protobuf, protobuf and the generated dfu_cc_pb2.py (in trussed/bootloader/nrf52_upload/dfu) seem to be incompatible:

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

I think in the long run this protobuf definition needs to be included in this repo to regenerate the python files as needed.
I'm happy to open a pull request that includes the .proto file and the newly generated dfu_cc_pb2.py. Let me know if you'd like me to proceed with that.
Hi :wave:
since a recent version of protobuf, protobuf and the generated
dfu_cc_pb2.py
(intrussed/bootloader/nrf52_upload/dfu
) seem to be incompatible:I regenerated the python definition from the protobuf definition found at https://github.com/NordicSemiconductor/pc-nrfutil/blob/master/nordicsemi/dfu/dfu-cc.proto, and it fixes the problem.
