Error when using search in 'Find and Merge Duplicate Contacts' page
An datatables warning pops up as a result of a error on the server (500) when searching for duplicate contacts (after selecting a rule) in the 'Find and Merge Duplicate Contacts' page.
- Go to the Find and Merge Duplicate Contacts page (route is civicrm/contact/deduperules?reset=1 or access it via Contacts > Find and Merge Duplicate Contacts).
- Create a new rule for detecting duplicates using their first name and last name only. I added First Name and Last Name as the fields and they have the same weight and the sum of their weights is the Weight Threshold to Consider Contacts 'Matching'. For example, weight treshold for First Name and Last Name is both 1 and the Weight Threshold to Consider Contacts 'Matching' is 2.
- Use the just recently created rule to look for duplicates. For the group, select 'All Contacts'.
- Attempt a search using the search bar on the top right of the list of duplicates; you should get the following error:
Should be able to search among list of duplicate contacts.
