API Spec was written based on Swagger 2.0 . I can see such behaviour when i am trying to create functional test case or creating a new project from the swagger definition. i am also seeing issues when i try to convert from Swagger 2.0 to OAS 3.X using Swagger editor site. i am suspecting issues with tags that were used in swagger definition and not supporting in OAS ERROR: com.eviware.soapui.impl.actions.UnsupportedDefinitionException Hi - I am seeing such issues while creating a functional test case using swagger 2.0. i see the Swagger is valid and i could check that by using my swagger hub as well. can you please let us me know if there is any way what could be parsing errors?
