Getting the following for TAK_PROTO=1

I had this issue too, it has to the with the flow tags implementation, commenting it out resolved the issue:

     flow_tags = ET.Element("_flow-tags_")
    _ft_tag: str = f"{pytak.DEFAULT_HOST_ID}-v{pytak.__version__}"
    flow_tags.set(_ft_tag, pytak.cot_time())

evaluates to the following for me: <_flow-tags_ pytak@Raiden-v6.2.2="2023-12-15T00:57:19.216182Z" />

@ is invalid in xml attribute
