You’re trying to pass a single " to Lua which doesn’t work because you use "" in your Lua code for the string.

When you change your definition for \uncover to

\unexpanded\def\uncover[#1]%
  {\ctxlua{
     distance = simplesteps.distance_to_step(\!!bs#1\!!es)
     ...
  }}

it works because the " is now only part of the string.
