I created the trigger to access information from different tables and update in the feature class ( enabled with Attachments) and sending email notifications in trigger itself. when i try to insert/update records from SQL Server and ArcMAP and ArcGIS Pro . it is working as expected. But when i try to insert/update records from Feature Service or Survey 123 app . It is giving errors . if we keep insert trigger , it is working as expected. if we try to append UPDATE trigger to it. it is throwing error. my obeservation is whenever inserting records using REST Feature service , The update trigger is also firing. Why ? How to overcome with this issue ? The feature class is not versioned.
