I've created a ReST API implementation using ExpressJS and MongoDB. Currently I am hosting the API on OpenShift. I have generated a documentation using apiDoc and I'm hosting the documentation on GitHub Pages.
When I open the documentation on my local machine it seems to work fine and I get content served from API instance on OpenShift. But when I try to make a call from the one hosted on GitHub Pages, I get the following error:
Error 0:
undefined
URL: https://faxad.github.io/xpress/#api-Inventory-GetItems
If I put the URL to the end point in POSTMAN, I get the results OK.
API: http://xpress-xpress-api.7e14.starter-us-west-2.openshiftapps.com/inventory
Why is it not working when I'm trying to access it from GitHub Pages?
