When searching for People in a SharePoint 2016 environment I encountered the following issue:
People are found, but the names of the persons found are not displayed.
Also: neither the profile pictures, nor the gray 'anonymous' profile images (for people that have not uploaded a photo) are shown
For debugging purposes I selected the 'Default Item' display template. When using this search display template "person.aspx" is shown as the item title.
I've already checked that the content access account is an administrator of the user profile service and has the 'Retrieve People Data for Search Crawlers' permissions added.
When using the Search Query Tool the following properties are shown in the result:
What other debugging steps can I follow / what could be the reason for this behavior?
