I'm wondering if the following is possible.
I have an aspx application (App1) that I currently access in SF using Canvas
I want to create a Lightning Component that contains that app (lightning:canvas component) - this seems to work
I then want to use Lightning Out to display App1 inside of a node.js Heroku hosted site
The lightning out piece seems to work but the canvas is empty. It seems to be looking for salesforce canvas files inside the heroku domain. So something like https://herokuapp.com/salesforcecanvascore.js which doesn't exist.
I'm just wondering if it is possible or if I missed something.
