Nx Express webpack build fails when nx serve command is called

Question

I have node.js 18.16.0 running on my machine. Configured a new nx workspace with react and later added express. When I serve the react app, it builds fine and launches the app but attempting to serve the express app, the following error is logged:

Error: Only URLs with a scheme in: file and data are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'
at new NodeError (node:internal/errors:399:5)

at importModuleDynamicallyWrapper (node:internal/vm/module:429:21)
at importModuleDynamically (node:internal/vm:106:46)

This may be related to webpack and the way nx configures webpack. Spent countless hours to try resolve it but no luck.

Any alternatives or workaround for this?

@nx/express@16.1.4 @nx/webpack@16.1.4

I had the same issue - I was using @nrwl/workspace@15.9.2 with @nx/express@16

I installed @nrwl/express@15.9.2 instead and it's working now
