Apex Replay Debugger not showing the content of variables correctly

[albarivas]

Summary

Trying to debug some Apex code, Apex replay debugger does not show the content of some variables, while System.debug does.

Steps To Reproduce:

Try to debug this code:

public with sharing class NewsletterGenerator {
    @AuraEnabled
    public static String generateNewsletter(String eventId) {
        Map<String, String> event = new Map<String, String>();
        event.put('id', eventId);

        ConnectApi.WrappedValue eventValue = new ConnectApi.WrappedValue();
        eventValue.value = event;

        System.debug('ALBA debug:' + event);
        System.debug('ALBA debug:' + eventValue);

        return '';
    }
}

Expected result

event and eventValue should show a value inside the replay debugger panel, same as I can see the value of those variables through system.debug:

Actual result

Hi @albarivas, I have not been able to reproduce this issue. When you mention you're trying to debug some apex code, what are the exact steps you follow for the same?

Hi @albarivas, can you provide us with your debug log to see what is going on?

[albarivas]

What I did was:

1- Deployed the NewsletterGenerator class (with a few more lines after the code I pasted, that are not important for debugging)
2-Started the apex replay debugger
3-Launched an action on my org that called the class
4-Downloaded the debug log (attached)
5- Launched apex replay debugger with the log file

And then I got the result you see on the screen, the event variable looks empty in the replay debugger, while if you take a look at the system.debug statement on the debug log it's not.

Let me know if it helps!

I was able to repro with that log file. My question now though is if in step 2 you meant you started Apex Interactive Debugger, is that the case?

@CristiCanizales it's the apex replay debugger, started capturing logs is probably more correct :)
