The user has a Flow that should send out e-mails to users based on their time card information. Recently, this did not work and e-mails were not sent out.
It was found that some changes had been made to the Flow and erroneous data pills were being utilized (there was a data pill referencing a step which no longer existed in the Flow).
It was noted that the action being performed relied on the information stored within the data pill. As a result of the data pill being broken, the functionality which was using it also broke.
Resolving the erroneous data pill fixed the issue.
