Explanation
The consultant should verify that trigger handlers were loaded into production when troubleshooting the issue of only the contact record being created when a contact record is created and a Community user is supposed to be created leveraging Table-Driven Trigger Management (TDTM) for the school that is implementing Salesforce with EDA to track parents and students in a community. Trigger handlers are classes that contain the logic for EDA triggers and can be controlled by Trigger Handler records. Trigger handlers need to be loaded into production before deploying declarative customizations or enabling features that depend on them.
The consultant should verify that trigger handlers were loaded into production by checking if the EDA_TDTM package was installed or if the Trigger Handler records were created. The community being set to Active or declarative automations being deployed successfully are not steps that the consultant should verify when troubleshooting the issue of only the contact record being created when a contact record is created and a Community user is supposed to be created leveraging TDTM for the school that is implementing Salesforce with EDA to track parents and students in a community.
