KB-1148 "Details: ERROR:EVAL:@reason=index" error thrown when using escalations, timers, and exception flows


Intermediate events include escalations, timers, and exception flows. When calling a rule in one of these intermediate events (in the Escalate at the date and time specified by this expression setting, for example), the following error is seen:

Details: ERROR:EVAL:@reason=index 


This can happen if the definition of such a rule or the expression itself is using load(). These functions are supposed to be used only inside SAIL forms. See the documentation for load() for more information.


Refrain from using load() anywhere outside SAIL forms.
