When trying to convert MRT file <updates.20030201.0023.bz2> I get the following error:

Hi,

Thank you for using mrtparse ❗
In my environment, there were no errors.
Could you tell me which version you are using ❓

$ python3 -c "import mrtparse; print(mrtparse.__version__)"
2.1.0
$ mrt2json.py updates.20030201.0023.bz2
[
  {
    "timestamp": {
      "1044087837": "2003-02-01 17:23:57"
    },
    "type": {
      "16": "BGP4MP"
    },
    "subtype": {
      "1": "BGP4MP_MESSAGE"
      (...snip)
      ],
      "nlri": [
        {
          "prefix_length": 24,

        }
      ]
    }
  }
]

from mrtparse.

I am running mrtparse 2.0.1 in python 3.10.2 and macOS 12.2.1

from mrtparse.

I changed the version and tried it, but there was no problem...

$ python -c 'import mrtparse; print(mrtparse.__version__)'            
2.0.1
$ ./mrt2json.py updates.20030201.0023.bz2

    "type": [
      16,
      "BGP4MP"
    ],
    (...snip)
      ],
      "nlri": [
        {
          "prefix_length": 24,

        }
      ]
    }

Your download data might be broken, so could you check the checksum ❓
In my environment, the checksum is as follows:

$ md5sum updates.20030201.0023.bz2                                    
2e15294482ff06f580fc4d6c218a3128  updates.20030201.0023.bz2
