Encountering an exception where a frame with origin "https:domain1:port1" is being blocked from accessing a frame with origin "https:domain1:port2". The error occurs at the code snippet "window.parent.Xrm.Utility.openEntityForm("entityName", null, parameters, windowOptions);" in MS CRM 2015
We are integrating a custom page into the sitemap directly (not within an iframe of any entity) by specifying the CustomWEBAPPs’URL at the Sitemap level. However, when trying to access the XRM of the parent page, we encounter the above-mentioned error.
This functionality works properly in IE11 but results in the stated error in Chrome and Firefox browsers.
Has anyone else experienced this issue? Any assistance would be greatly appreciated.
Thank you
