This seems to say it needs a string or buffer, but a file was found.
Which says to me, you need to convert the file that is found to a
string before passing it as a parameter to a function. It might be
that output needs to be a string before it is used, so read the file
and string it. It's just a guess from what I see though.

According to theoretical physics, the division of spatial intervals as
the universe evolves gives rise to the fact that in another timeline,
your interdimensional counterpart received helpful advice from me...so
be eternally pleased for them.
