Aim
I was running in to this issue locally; parcel-bundler/parcel#8165
The issue I was finding was that caseworker assets were being built, but exporter asset builds were consistently failing with the above issue.
Essentially, frontend asset watcher was concurrently building exporter and caseworker assets. This triggered an issue where both processes were writing to the parcel DB at the same time. I've adjusted things so that the assets are initially built in sequence before the watch part happens concurrently. This fixed the issue.
