Hi community, I am working on What in my mind is adding a type transformer at and adding a corresponding type at flyteidl. If this is correct, what's the flow of testing it? 1. Compile the proto and convert it as a python package. 2. Use the new generated package to test flytekit. Is it correct?

Hi. Welcome. you don’t really need to create a new type in IDL. you could just translate date to Datetime in idl • to_literal: python date -> literal.duration • to_python: literal.duration -> python date
