In cq:dialog I call this acs-common generic list(countries), it works in dev(on-premise) author, publish and dispatcher. But in prod(cloud) It is working in author & publish alone not working in dispatcher. when I checked the cached page html from dispatcher against Dev, the portion of dropdown list code is not injected in the html.
RHEL 7
AEM 6.5.1
ACS: 4.2.2
Dispatcher 4.2.3
