This appears to be caused by the @nx/webpack/plugin

Any workaround ? I get the same when I try to add an express application to an existing monorepo with React MFE

I had to run the command by disabling plugins to get a new app created

NX_ADD_PLUGINS=false yarn exec nx g app my-app --bundler webpack --e2eTestRunner none --directory apps/my-app --verbose

It works on my PC (Ubuntu), but I'm not sure if all the configurations in NX are correct.

Hey all, I have not been able to reproduce this. Could someone please provide a repo on the latest version that we can pull down where nx g @nx/nest:application will fail?
