Error on fetch for .js
When running gulp on a windows machine, I get this error

Hi @visardida!
Could you upload a reproduction somewhere so that I can take a look at it? With this log alone, I can't help you.
One thing you could do is enable debug logging in the scripts-javascript-dist gulp task. You'll find it under node_modules/modern-web-dev-build/dist/gulp/tasks/
There are two lines to uncomment. Once done, the log should give you a bit more information. It might simply be that you have an import statement somewhere with a wrong path or with a file extension where you don't need one.
I'm getting a very similar error, also on a Windows machine, on a fresh yeoman run, no changes to any file. Repro steps are pretty simple: mkdir PROJECT_NAME && cd PROJECT_NAME && yo modern-web-dev && gulp default
I couldn't find any commented lines in the scripts-javascript-dist gup task's .js, but that file looks a lot like its been pre-transpiled from something.
For me, it looks a lot like its not properly resolving relative paths it finds in a require.
Here's the relevant log:
