   Seems like the "generation.jl" file is not in the registered package?

   checking .julia/packages/JSONSchema shows only "JSONSchema.jl schema.jl validation.jl"

   Installing the package via git solves this though.

   The master branch currently contains a breaking and unreleased v2.0.

   For the latest released version, see https://github.com/JuliaIO/JSONSchema.jl/tree/v1.5.0

   Schema generation was added in #80. Current master identifies itself as version 1.6.0, and this example passes on unchanged commit 10199bc0eab591bf9916131b9de2d18f4775d2da with Julia 1.13.1:

   using JSONSchema
   
   struct Parameters
       count::Int
       label::String
   end
   
   s = JSONSchema.schema(Parameters)
   JSONSchema.validate(s, Dict("count" => 1, "label" => "ok")) # nothing

   The General registry still ends at version 1.5.0, so the reported error remains valid for the latest registered package. Installing the development branch provides the generator; a registered version containing it is still needed before closing this issue as fixed for ordinary package installation.
