Editing GA declaration to add end date causes Civi to hang
Running Drupal 7.73, CiviCRM 5.30, GA extension 3.4.5
Editing an existing GA declaration to add an end date results in session hanging (with spinning triangle), although the new end date is stored in database. Debugging console message is:
[Error] Failed to load resource: the server responded with a status of 500 () (edit, line 0) https://weyarun.org.uk/drupal_demo/civicrm/contact/view/cd/edit?tableId=12158&cid=12158&groupID=10&action=update&snippet=json
Other edits of the declaration appear to work as expected.
