I’ve been stuck on this issue for a long time. It uses IntelliJ’s own Ktor Wizard. The error message says that a feature of XML is missing, but I don’t know how to fix it.

It is not really kotlin related, but you need to find sax implementation library. Im not sure if this the correct one but check https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api/2.3.1
