[Classic Era] multiple lua errors

[FireReaver]

I've always been using this addon with Classic Era and never had many issues until recently when the addon now keeps piling up error stacks, despite I'm already using the latest version available compatible with Era:
[3.2.2 - https://www.curseforge.com/wow/addons/bananabar3-wow-classic-addon/files/3308068) - 450.85 KB - May 13, 2021]

Can you tell me how to fix it, please?
Thanks a lot
