Type should be like this:
type ServiceInfoSerName string
type ServiceInfoTransportId string
type ServiceInfoVersion string

Start with the Mp1.yaml definition linked in the issue and compare its ServiceInfo attributes with the generated Go declarations for ServiceInfoSerName, ServiceInfoTransportId, and ServiceInfoVersion. Trace the Swagger Editor/code-generation path used by the report and verify that these attributes generate as string aliases rather than empty structs; no local files or tests are named.
