Nebula Logger: Tags and Tag Entries missing after configuration

[CorradoGianluca]

Hi,
We have installed the Nebula Managed package in our Sandbox org.
We configured rules in the Logger Tag Rules Custom Metadata to automatically generate tags. However, when we execute an action that publishes a log, no Tags or Tag Entries are created.
Please find the configuration screenshots attached below.
We also attempted to add tags programmatically via Apex, but even with this method, they are not being created.
Can you please assist us?

Logging sObject Handler Config:

Logging Parameters:

Logging Tag Rule:

Logger Tags:

Example Log Entry:

Hi @CorradoGianluca thanks so much for sharing all of the screenshots! Could you also check under Logger Parameters for the record Use Topics for Tags? It should be set to false (default) to use Logger Tag & Log Entry Tag objects. If that's already the case, then I'll have to do some more research - everything else looks correct 🤔

Hi @jongpie, thanks for your reply.
I checked the Logger Parameters, but I can't find any record named Use Topics for Tags.
I'm sharing the configuration JSON containing all records and their values (they have remained unchanged since the installation, so we haven't touched them).
Looking forward to your response, thanks a lot!😊

Thanks @CorradoGianluca! It's a little strange that the parameter record for 'Use Topics for Tags' is missing, but I don't think it's the source of the problem (the code will use false if the record is missing).

Could you tell me which version of the managed package you're using? And could you try running this Apex script? This will (try to) save the data synchronously (instead of the normal async way via the event bus), which might help surface any exceptions (or at least confirm that you're not seeing any exceptions):

Nebula.Logger.info('hello, world!').addTag('some test tag');
Nebula.Logger.saveLog(Nebula.Logger.SaveMethod.SYNCHRONOUS_DML);

[CorradoGianluca]

@jongpie We are using version 4.16.

Actually, running the code you suggested throws an exception. Here is the error message:
FATAL_ERROR|System.NullPointerException: Argument cannot be null.
and it didn't set any tags.
