Ah, pcall() is passed a _function_, so you need to do this:

local ok, s = pcall(function() return filters:add(123) end)

Here ok will be true or false depending on whether the code threw an
error; s will then be the error, or the result of the function if
successful.

In your case, could also do

local ok, s = pcall(filters.add,filters,123)

since pcall() can take arguments.
