tempFileDir: './tmp',
//debug
debug: true
},The Dockerfile was extended to create /app/tmp otherwise uploads fail with "ERROR: EACCES: permission denied":
COPY --from=builder --chown=nextjs:nodejs /app/.next/standalone ./
COPY --from=builder --chown=nextjs:nodejs /app/.next/static ./.next/static

The exception text is from the MissingFile error.
In some rare cases the upload succeeds and the log output is there. I guess there are some problems with file I/O and some exceptions are not caught. It runs fine in a local build. Debugging in Docker is not easy because Payload gets bundled and cannot be monkey patched.
