Hi David, the book is completely outdated. We usually name operations following the Rails convention (e.g. Comment::Operation::Create) and turn off the trb-loader gem via config.trailblazer.use_loader = false, and it works like a charm.

Ah dang, I was really enjoying the book, it was just a very gentle introduction to Trailblazer, any plans for updating it?

By the way, this error went away with gem "reform", '~> 2.2.4'
