Actions Taken:

Chrome Dev Tools Error Shown:

This is the error message that appears when I try to click the Submit button on the Select Link window:

angular.min.js?cdv=1987298381:63 TypeError: Cannot read property 'split' of undefined

This error message also appears in Chrome Dev tools with a little X next to it. It appears to be happening in the angular.min.js file as well:

GET https://localhost:44352/cms-management/backoffice/UmbracoApi/Entity/GetUrlAndAnchors?id=umb://document/57619124ec0b47f3ba2e13e28947e799 417e

Things to note:

1. Linking to a page within Umbraco works perfectly
2. If I create a new link, I can type an external URL in the URL box and save just fine
3. The Media Picker option also isn't working. If I try to insert an image onto the page, it only populates paragraph tags.

I see there has been a lot of conversation around this issue but I can't seem to find a legit solution. Can anyone help me?!!!
