I'm trying to run the command ng add @angular/pwa --my project name so that I can implement service workers in my angular project but the error that I'm returned is "The add command requires to be run in an Angular project, but a project definition could not be found." If anyone can shed some light on what I can do to get past this error it would be much appreciated. I was upgrading from Angular CLI version 1.49. I have a feeling it has something to do with the angularcli.json file since the new version uses angular.json file. This is also an exception when I try to use ng serve : Workspace needs to be loaded before it is used.
