Marking required fields in OpenApi swagger document
Currently in the version of the OpenApi dll we are using, the required fields aren’t marked. For eg: In the Leads/QualifyLead the Odata XML shows that these fileds: CreateAccount, CreateContact, CreateOpportunity, Status are Nullable=false (meaning required)

But the OpenApi swagger doesn’t show that these fields are required:

Steps to reproduce
Use any bound/unbound action and check the metadata and compare the OpenApi swagger generated and you will notice the nullable fields are not set as required.
Expected result
The OpenApi swagger marks the required fields and returns it as a part of the swagger document
Actual result
Currently in the version of the OpenApi dll we are using, the required fields aren’t marked.
Which version of the conversion library are you using?

I think currently we are using 1.1.2
You mean 1.0.0-beta8 for this lib. Please upgrade to latest and see if you have the same issue
I am assuming the upgrade fixed this issue. Please re-open if this is still a problem.
