Problem statement

I am using this fantastic project to flatten some big swaggers (because a 3rd party app I use can't use swaggers if they are not flattened sadly). When I try to flatten the swagger, I receive the 'Object has no field "components"' error no matter what --with-flatten option I choose. But clearly, there is a "components" field that contains 3 more fields: schemas, headers and responses. It worked in the past (mainly with 2.0 swaggers), but this is the first time that I am using an openAPI 3.0.0 swagger - hence this issue. Also, I can not modify the swagger in any way since it is provided by another company and I have to use it as is. Ps. I'm new to this go-swagger, please forgive me if I shouldn't have posted here. Thank you all!

Swagger specification

For security reasons, I can't share the swagger but I can share its overall structure:
