Collection display page url not getting mapped properly

Issue

• We have a collection page with web content cards and want to link those cards to the display page URL.

Environment

• DXP 7.4

Resolution

• By default, a Web Content's Display Page selector is set to "Default", but a fresh environment does not have a Default Display Page Template.
  
  You can reach the expected results following the steps below:
  
  1. Go to Design > Page Templates, select the Display Page Templates tab
  2. Create a new Display Page Template for Web Content > Basic Web Content, publish the page
  3. Using the kebab menu of this Display Page Template, select "Mark as Default"
  4. Create a Web Content
  5. Create a Manual Collection and add the Web Content to it
  6. Create a Content Page
  7. Add a Collection Display fragment
  8. Select the created manual collection for the fragment
  9. Add a heading fragment into the collection fragment
  10. Map the Display Page URL to the heading
