Steps to Reproduce
Create an SLA rule that uses the Advance Flow action.
Or
Call the ResumeFlow activity to move the flow from the current assignment through a specified flow action.
Root Cause
The SLA Deadline is triggered. However, a broken queue item is created which contains a page level error message.
The flow action invoked by the Advance Flow action is configured to execute a post 'After this action' activity. This activity validated the user input and executed a Page-Set-Message method to set page messages when the input is invalid.
The below image displays the Flow Action assigned with Post-processing activity.
In this case, SLA processing continued the flow automatically. These page messages stopped the progression and caused the broken queue item.
When the Advance Flow action or ResumeFlow activity are used, the same validation criteria must be met to execute the flow action.
Resolution
Perform the following local-change:
Update the validation logic to consider situations where a flow action must be submitted automatically without valid user input.
For example,
Skip the validation or set the required fields before advancing the flow.
