I'm on mobile, but without checking, I think the problem is here
rule pairlist { <pair> * % \; }
Specifically it's the missing %
rule pairlist { <pair> * %% \; }
JSON doesn't allow trailing commas or semicolons, so JSON::Tiny uses just %.
Your data does have trailing semicolons, so you want to use %% instead.
Also why did you change <object>, without actually changing anything?
