I tried open tooling following the instruction from Ext JS open tooling guide here: https://docs.sencha.com/extjs/6.7.0/...n_tooling.html

generated a modern desktop app, ran in a browser, created a production build without any problem but then I got an error when trying to generate new view package using either "ext vp testview" or "npm run createview testview" command.

The first command returns the error "Not a Sencha Cmd project - no app.json found". The second command returns "[ERR] Unknown command: "viewpackage".

I'm using [email protected], [email protected], Sencha ExtGen v6.7.0 Professional Edition, and Sencha Cmd v6.7.0.63.
