How can I update this mod?

[vvbnspdj07]

I have the mod on 1.21 and the scripts for 1.22 . How do I update it? It's a single file. When I try to merge them this is what I get:

Error [modpersistentappearances]game\player\playerwitcher.ws(2332): Could not find function 'GetAbilities'

Error [modpersistentappearances]game\player\playerwitcher.ws(9122): Could not find function 'GetAbilities'
