What's wrong with this crawling hose?

Colleagues, I’m just starting to master Zeek and I apologize for the variety of questions.

Our good friend from the first chapter of the Book of Genesis, instead of crawling in with a package of paradise apples, sent an email.
In it he hissed the following with displeasure:

Traceback (most recent call last):
  File "/usr/local/bin/trace-summary", line 1115, in <module>
  File "/usr/local/bin/trace-summary", line 508, in readConnSummaries
    parseConnLine(line, field_sep, unset_field, idx, max_idx_1, is_json, scope_separator)
  File "/usr/local/bin/trace-summary", line 844, in parseConnLine
  File "/usr/local/lib/zeek/python/SubnetTree.py", line 103, in __getitem__
    return _SubnetTree.SubnetTree___getitem__(self, cidr)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd9 in position 0: invalid continuation byte
        0,06 real         0,05 user         0,00 sys

I installed Zeek from FreeBSD ports, and in theory, all the necessary modules should have compiled.

What’s unhappy about this scaly reptile?

Thanks in advance for your advice,

I found the quote I gave on several other resources and also without an answer.
Is this problem with Python really so serious that no one can solve it and everyone is embarrassedly silent?

Dear Benjamin!

Thank you very much for this link. The problem is that I created this “issue”. Despite all the mental difficulties, I have not forgotten about it yet.

Therefore, I would be more pleased with your advice on solving this problem. However, in any case, thank you very much.
