CiviCRM Export, Saved Export Field Mapping that contains custom fields which have been disabled or deleted are still loaded as "clear" values and cause the export download to fail with "DB Error: no such field"
CiviCRM Export, Saved Export Field Mapping that contains custom fields which have been disabled or deleted are still loaded as "clear" values and cause the export download to fail with "DB Error: no such field".
This is complicated further because the user cannot remove the "clear" fields from the field export list at all and as a result, renders the Saved Export Field Mapping defunct.
The disabled or deleted fields are listed on the field export page as "clear", see screenshot below.
