Name field is missing after conversion from swagger 2.0 to Open API 3.0

Hi there,

In Swagger 2.0, there is '- name: pickup items' in the yaml file. After converted to Open API 3.0, this is missing and causing integration failed.

May i know how can i address it in Open API 3.0 YAML file?

Thanks.
