This looks like a bug, are you able to provide a minimal but complete Goa design that reproduces the issue?

Thanks for the quick response.

Sure, here you go:

package design

import (
	. "goa.design/goa/v3/dsl"
)

var _ = API("goaBugRepro", func() {
	Title("Goa Bug Repro")
	Description("Minimal example to reproduce a bug found inside goa")
})

var _ = Service("bugService", func() {
	Method("createBug", func() {
		// Generation works if the result is just one Bug and not an array of Bugs.
		Result(ArrayOf(Bug))

		HTTP(func() {
			GET("/bug")
		})
	})
})

var Bug = Type("Bug", func() {
	Attribute("id", Int)
	Attribute("nested", func() {
		Attribute("nestedString", String)
		Attribute("nestedNumber", Int)
	})
})

While creating the repro I noticed that the bug only appears once I return an array of bugs as result of the method createBug. When just one Bug is returned, everything's fine.
