hi @kevgeni

You can try to add the parameter type to Configuration.Auditing.IgnoredTypes

I had this issue today and it was quite hard to debug. The stack trace was not very helpful as it was inside of the AuditingHelper and would not very show what it was trying to serialize nor where it was trying to serialize it.

Disabling audit logging would temporarely fix the issue (https://aspnetboilerplate.com/Pages/Documents/Audit-Logging)

I implemented a custom abp IAuditSerializer and replaced the default implementation with mine and added a try-catch inside. This allowed me to find that what was failing to be serialized was … a repository ??? The log did show that MyCustomTableRepository but I wasn’t sure what was that.

WARN 2022-10-12 13:29:57,131 [orker] Abp.Auditing.AuditingHelper - Newtonsoft.Json.JsonSerializationException: Self referencing loop detected for property ‘manifestModule’ with type ‘System.Reflection.RuntimeModule’.

I found that one of my abp ApplicationService had a method definition like this [HttpPost] public async Task<List<MyCustomDto>> GetMethodA([FromServices] IRepository<MyCustomTable> MyCustomTableRepository, [FromBody] GetMethodAInput input) { }

The default implementation of abp will try to serialize all input parameters, including the injected FromService repository. serializing the repository will fail… I moved that injected repo from the method to the controller and fixed the issue.
