also running into the same. appears it hasn't been updated for 1.32. dev hasn't updated since 2020 so i don't think this project is still alive, unfortunately

It looks like Blizzard changed how they're storing some of the reforged player metadata (player id number, battle tag, clan, portrait, and maybe more) with patch 1.32.10. I'm not seeing the clan information in it anymore, but it looks like they may have added in the portrait ID? I can't change my portrait in WC3 to test it out for some reason, is that functionality broken right now? I also haven't looked much at how patches 1.33 and 1.34 impact it, and we've got 1.35 right around the corner.

The w3gjs package handled this update by using a protobuff serializer with a given schema. I tried running some replays through it though, and it doesn't look like it's picking up all the information that's there.

I guess getting this working will entail looking at that particular segment of the replays byte by byte for all the patches from 1.32.10 forwards, and coding up whatever variations appear. I don't know if Bnet replays will have different info in them than other games too, like Warcraft 3 Champions. This will take a bit to sift through.
