Advanced Troubleshooting and Debugging Mastery Hub: The Indu

When debugging a complex Adobe Analytics implementation involving custom variables and eVars, what is the most efficient initial step to isolate a potential data discrepancy in a specific user journey, assuming general site functionality is confirmed?

A client reports that a critical conversion event is intermittently not being tracked in Adobe Analytics. During your debugging, you observe that the JavaScript trigger for this event fires correctly on the website, but the corresponding hit is sometimes missing in the debugger. What is the most likely cause of this intermittent loss, and what is the primary debugging technique to confirm it?

You are tasked with debugging a situation where a specific custom dimension (e.g., a custom eVars) is showing inconsistent values across different pages, even though the JavaScript logic for setting its value appears correct. When using the Adobe Experience Platform Debugger, you notice that the `s.eVarX` parameter is present in some hits but not others, or its value changes unexpectedly. What is the most advanced debugging approach to pinpoint the exact line of code responsible for this inconsistency?
