CDP domains start disabled. A client that attaches and immediately navigates receives no request or response events unless Network.enable was sent first, and the same applies to Page, Runtime, Log and DOM. Because the navigation itself still works, the failure looks like a protocol that silently dropped events rather than a missing setup call.
Enable every domain you intend to listen to before triggering the work, and remember that enabling is per session: a new target, such as an out-of-process iframe or a newly opened tab, arrives with everything disabled again, which is why Target.setAutoAttach with waitForDebuggerOnStart exists. Some domains also replay accumulated state when enabled, Page.enable among them, so the order of enable calls changes which lifecycle events you observe.
