 Business Requirement: Ensure userID is set in the data layer and mapped to eVar5, and used for visitor identification.

 Issue Identification:

The userID data object must be available in the data layer before the Adobe Launch rule executes.

 Explanation:

visitorID is not available in the data layer when the Adobe Launch rule runs: If the visitorID is not present in the data layer at the time the rule executes, the mapping to eVar5 will not occur, resulting in an empty eVar5 report.

 Verification: According to Adobe Launch documentation, the timing of data layer availability is crucial for rule execution. Ensuring data is present before rules execute is necessary for accurate data capture (Adobe Launch Implementation Guide).
