Error: Registry returned 404 for Get

I keep getting this error in my output when trying to package iOS through Ionic cloud “Error: Registry returned 404 for GET on https://registry.npmjs.org/[MyAppName]”. I’ve followed a few other forum posts that I could find to no avail. Any help would be much appreciated!

I was able to solve the issue by running
ionic state clear --plugins
Not all of the Cordova plugins cleared on the first pass. So I had to manually delete them from the plugins directory. Then ran:
ionic state restore --plugins

This appears to correct the issue.
