We migrated a custom workflow to production and we started seeing below error in notifications. There is no change in this part of the code that we pushed with the new version though.

ERROR_STACK=
Wf_Notification.GetAttrblob(17784094, PDF_ATTACHMENT_SUPPLIER, text/html)
WF_XML.GetAttachment(17784094, text/html) WF_XML.GetAttachments(17784094, http://oracle.com:80/, 2785)
WF_XML.GenerateDoc(oracle.apps.wf.notification.send, 17784094)
WF_XML.Generate(oracle.apps.wf.notification.send, 17784094)
WF_XML.Generate(oracle.apps.wf.notification.send, 17784094)
Wf_Event.setMessage(oracle.apps.wf.notification.send, 17784094, WF_XML.Generate)
Wf_Event.dispatch_internal()

Does anyone encountered this issue in the past, pls suggest.
