Getting error when using operator with text objects

Nvim: 0.4.3

I am getting the below error when I do something like dai or cai inside any function or class.

Error detected while processing function <SNR>45_HandleTextObjectMapping[1]..<SNR>45_TextObject:
line  180:
E447: Can't find file "class" in path

I feel like I'm commenting under every issue in this repo, but I don't see this behavior in my fork.
