Direção de pesquisa

Start in Evtx/Nodes.py at get_variant_value, referenced by the traceback at line 468, and trace how the parser handles the failing value 108. The report provides no sample EVTX file or reproduction steps, so first identify a way to reproduce the KeyError; done means the reported parsing path no longer raises it.
