Workflow Detail Page- User Defined Resource Error

Jay CamposMar 11 2026 — edited Mar 12 2026

Hello everyone,

Could someone please advise as to how to troubleshoot a user defined resouce error 555?

I imported an application into a seperate environment it has always worked before but this time around when I initiate an Oracle APEX Workflow the tasks and everything works well.

On Workflow Console I see the workflows but when I click on it and navigate to the Workflow Detail page (which has the workflow diagram and workflow parameters) I get user defined resource error - httpp status code 555 and error code ords-25001.

“The request could not be processed because an error occurred whilst attempting to evaluate a SQL statement associated with this resource. Verify that the URI and payload are correctly specified for the requested operation. If the issue persists then please contact the author of the resource.”

Would greatly appreciate any thoughts.

Update: Noticed it works on dev instance but not prod. Same application.

SQL Error Code: 600, Error Message: ORA-00600: internal error code, arguments
