Message_Parser example not working on latest pymodbus release

[CapraTheBest]

Versions

• Python: Python 3.8.1
• OS: Windows 11
• Pymodbus: 3.6.5
• Modbus Hardware (if used):

Pymodbus Specific

• Server: tcp/rtu/ascii - sync/async
• Client: tcp/rtu/ascii - sync/async

Description

When trying to decode any modbus message using the example called "message_parser.py" I get nothing, even if the message is valid and/or generated manually. I've tried running it with an old version (2.5.3) and there it worked flawlessly.

Code and Logs

Intended behaviour:

PS > python .\message_parser.py --framer socket -m 0812000000170104148000800080008000800080008000800080002004

documentation   = Read/write input registers.

    This function code is used to read from 1 to approx. 125 contiguous
    input registers in a remote device. The Request PDU specifies the
    starting register address and the number of registers. In the PDU
    Registers are addressed starting at zero. Therefore input registers
    numbered 1-16 are addressed as 0-15.

    The requested registers can be found in the .registers list.

Actual behaviour:

PS > python .\message_parser.py --framer socket -m 0812000000170104148000800080008000800080008000800080002004
