Error reproduction for metadata page error in ServiceStack 4.5.4
The error is seen when opening the metadata-page for the json-endpoint for the Hello-service /json/metadata?op=Hello
The HelloDetail displays info about a HelloDetail-class in another servicemodel-library, seen by the fact that it's showing the InternalInfo-property, not the Details-property.
The HTTP + JSON part showing the actual request and response examples, does however show the HelloDetails-object correctly.
The error occurs only when this condition is met: The response root class has a Wrapper-property, inside this wrapper-class, the HelloDetail-type is contained in a generic List.
