NPM >= v7.0.0 documentation is inconsistent with provided package-lock.json
The package-lock.json files provided in the template appear to be from NPM v6. ( https://gitlab.ubitech.eu/glass-project/wallet/dsu-blueprint-workspace/-/blob/master/package-lock.json )
The https://gitlab.ubitech.eu/glass-project/wallet/wiki/-/blob/master/README.md says its NPM V>=7.
But if you use NPM v7 or V8, the package-lock.version will be upgraded to a backwards incompatible version. (The package-lock.json should be commited for repeatable builds).
Please decide the right version (7 or 8), update the documentation README.md and notify the developers.
