Data on the left side of the multi-list is not loading if the user is a non-admin. I have multisite on a single node so on the data source I've put Sitecore query as StartSearchLocation=query:./ancestor::*[@@templatename->'Site Folder']&Filter=_templatename:some_template_name.
The above query returns the expected result for users with admin privilege, but not for the non-admin users. For non-admin users, its data keeps on loading and it does not return any result.
While verifying the ajax call found that there is a null exception on the call. Attached the screenshot below
I have verified the item permission for the Site Folder template and all its ancestors. Yet the issue exists for the non-admin users. I have reindexed the Master DB in Solr as well. Kindly let me know if any other suggestion or fix for this issue.
Thanks in advance.
