Learning Alert link not working after 19D upgrade

Content

Hello, 

We have recently built a learn alert using the alerts composer to notify users when they have been assigned new required learning within the past 24 hours. Within this coding we built a table that provided the user receiving the alert a link that would direct them to the learning. The code for this is: 

You can access the learning and book a space on face to face courses on Oracle Learning through the following links:
${AlertUtils.write("<table border=\"1\"><tr><th>Learning Item Title</th> <th>Assigner Name</th><th>Link to Learning Item</th></tr>")}
${AlertUtils.loop('learnerLearningRecords','<tr><td>${learningItemTitle}</td><td>${assignerDisplayName}</td><td>Click <a ${href}="${assignmentDetailsDeepLink}">here</a> to start the learning!</td></tr>')}
