Steps to reproduce the issue:

Hi,

I am publishing event in one microservice and listen in another. I've noticed that when I create or delete entities in the distributed event handlers the CreatorId or DeletorId record fields not added. Any ideas?

Thanks.

Hi,

Can you send your entity contents and if you have a configuration for AbpDistributedEntityEventOptions?

Hi,

CreatorId and DeletorId are auto-filled using ICurrentUser during HTTP requests. However, in distributed event handling, events are processed asynchronously in another microservice without the original HTTP context, so ICurrentUser data isn’t available, leaving these fields null. I suggest adding CreatorId and DeletorId to the ETO object when publishing the event and then setting them in the event handler as follows:

test.CreatorId = eventData.Entity.CreatorId; test.DeleterId = eventData.Entity.DeleterId;

Hi,

Even if I'll set them manually, as you suggest, the repository Update and Delete methods will set them to null.

Yes, you are right. Instead, you can try to change the current principal, which will change the CurrentUser as you stated in the related scope.

We have a section in our documentation for changing the current principal, which you can check out at https://abp.io/docs/latest/framework/infrastructure/current-user#changing-the-current-principal

You basically, need to inject the ICurrentPrincipalAccessor service, and use its Change method (which is a disposable method, so you should create a scope as stated in the documentation) and specify the CurrentUser as you wish. With this way, it should set the CreatorId and DeleterId.

Let me know, if it fixes your problem. Regards.
