Reproduction Steps
I managed to bypass the issue in the next.config.mjs like this:
serverExternalPackages: [
'@payloadcms/db-d1-sqlite'
],
OpenNext doesn't yet support Turbopack as per this issue, therefore even if the Turbopack build didn't have errors, it still wouldn't work on Cloudflare/D1 currently, but OpenNext+Turbopack compatibility is currently being worked on, so it'd be nice to fix this build error into Payload as well beforehand.
