Why can't I add NPM package to the project? I think it's a bug

For example, years ago the first version of this package was released, but because the repository URL information was not included in the package.json at that time, a new version was updated with the URL. In this case, the package should be able to be added as a project. The current situation I see is not like this.

This is not an isolated case, Please check it. Thank you!!
