Receiving the following Lua error, despite the fact that my character is Beast Master spec:

Message: Interface\AddOns\HeroRotation_Hunter\Survival.lua:140: function arguments expected near 'and'
Time: Fri May 28 18:30:54 2021
Count: 4
Stack: Interface\AddOns\HeroRotation_Hunter\Survival.lua:140: function arguments expected near 'and'

Locals: <none>

This occurs upon initial UI load, but doesn't seem to reappear and Beast Mastery rotation appears to work just fine.

This was already fixed in previous commit 08ee779

Either grab the new file from github, make the change to the file manually, or it will be updated in the next release (which I'll probably push tonight).
