Hey @BullDogBg, this often means that there’s a problem somewhere in your package.json or dependencies that disrupts the pnpm install process. Express never actually gets installed, and it’s the first package that’s required in your code path, so Node throws an error when trying to find it - in other words it has nothingh to do with Express directly; that’s just the first problem your project encounters.
Running pnpm-install or its close mat enable-pnpm in your project’s console (see https://support-assets.glitch.me/logs-pane-console for how to get there if you don’t know how) and watching the output can often show you the actual source of the problem. If you want to share your project name someone can take a closer look.
