He team,

We are moving from trail to licensed version. We followed the given instruction from Ignite UI Licensing (infragistics.com) .
And we added below lines in file .npmrc 

@infragistics:registry=packages.infragistics.com/.../
//packages.infragistics.com/npm/js-licensed/:_auth=my_token
//packages.infragistics.com/npm/js-licensed/:_password=pass
//packages.infragistics.com/npm/js-licensed/:username=username!!infragistics.com
//packages.infragistics.com/npm/js-licensed/:email=username@infragistics.com
//packages.infragistics.com/npm/js-licensed/:always-auth=true

After run  ig upgrade-packages command we got the following error
