I am completely beginner to SAP world and about to complete the training, "Building side-by-side extensions on SAP BTP", I stumbled upon such error message and cannot start the CDS application using, cds watch command. It worked in the past but suddenly this happened. npm update and npm ci did NOT work. Can it happen due to any recent updates in package.json dependencies.? Can anyone support with this please? Many thanks.

@patricebender Thanks for feedback. Here is output for cds --version

You are using cds@7.6.2, I was able to reproduce the issue with this version.

→ Please run `npm install` again, the error has been fixed with `@sap/cds@7.9^`.

Even after running the npm install, the error was still there but then I had to manually update package.json and package-lock.json with "@sap/cds": "7.9.2" and then cds watch started and everntually application.

But it worked, thanks @patricebender. Now I'm ready to take over next challenge already ; )
