redgreen has asked for the wisdom of the Perl Monks concerning the following question:

Something in my data has changed, but I'm not sure what, or where to look. I am getting this error from the $tt->process call:

undef error - Usage: Template::Stash::XS::set(root, ident, value, ...) + at (eval 86) line 3.

Can some monk knowledgeable with TT offer some insight into what this means, and where I should start looking?
