Do you need a rebase? This is showing as your change / commit, even though it was merged into develop 14/03.

Also - there appears to be 3 references to /develop in the spec file, rather than /v6.1.0, (this line for example).

Do you happen to know why that is the case?

I'm getting the following error in the IDE when viewing the spec file locally...

Something went wrong...

Removed the references to develop from the spec file. Attempted a rebase however it would appear the section of code in question was actually deleted in develop due to conflicts with Open API v3.
