@AshishR6 The error happens because pyBody is a short text property with a 256-character limit, but your email body is large HTML content, so Pega is truncating it and failing. To fix this, save your email body into a property of type “Text” or “Long Text” instead of using pyBody. Then pass that property to the SendSimpleEmail activity or switch to using CorrNew/SendEmailNotification, which support long HTML content. Also check your class mapping to ensure the property is stored in a CLOB column. Once you move the email content out of pyBody and into a proper long-text field, the email will send without this truncation error.
