I have created some custom ID tokens to the auth0 standard of using a namespace such as ‘[http://www.test.com/roles](http://www.test.com/roles)’ and assigned an array of roles (strings) to the said idtoken.

Problem is I am now in vuejs/javascript, I have received my id token but how do I reference a variable with the name ‘[http://www.test.com/roles](http://www.test.com/roles)’ as the second I reference user.[http://www.test.com/roles](http://www.test.com/roles) I get an error because of the ‘:’ colon in the variable name and the 2 slashes are being treated as comments.

this.$parent.$parent.user.[http://www.stutor.com/roles](http://www.stutor.com/roles) is erroring out due to the colon and the slashes in the variable name.

Please help!!!  
Thanks

Hi @wolfbrownie1995,

You’ll need to use the bracket notation instead of dot notation when the key is a URL like that

e.g.  
`user["http://www.stutor.com/roles"]`

Some more example are here: [JSON Literals](https://www.w3schools.com/js/js_json_objects.asp)
