Question plugin throwing could not pass event error

[turbothewolfhog]

I just installed a plugin called ChatManager, which I'm using alongside DiscordSRV and EssentialsX, so I could use an Auction House plugin with Vault. But every time someone joins or leaves my server, the following happens. First, joining:

Can anyone help me decipher what's happening? My server is running PaperMC 1.20.2, with Viaversion, Viabackwards, and Viarewind to support older Minecraft versions, and Geyser and Floodgate to support Bedrock connections.

ChatManager is throwing errors. It's probably best to contact the author of the plugin to ask for assistance.
