Unable to process NCEP BUFR files - exits with StopIteration

[Plantain]

Something is throwing an exception deep inside pybufrkit while processing NCEP bufr files and I'm not able to figure out where it's coming from.

Data file:
http://static.skysight.io/ncep.bufr.gz

Versions:
% pybufrkit --version
pybufrkit: 0.2.20

% python --version
Python 3.10.6

Output:
% pybufrkit decode --continue-on-error -m /tmp/ncep.bufr > out.txt

StopIteration

The above exception was the direct cause of the following exception:
