Unable to find a method called ''. Candidate methods are:

When updating NuGetTrends's Serilog.Settings.Configuration from 3.1.0 to 3.2.0-dev-00244, one of the sinks stopped working.

The configuration is public, but basically this sink is the culprit:

"Name": "LogzIo",
"Args": {
	...
}

From the package:

<PackageReference Include="Serilog.Sinks.Logz.Io" Version="2.2.1" />

I have two sinks there configured via appsettings.json and the other (Sentry) works properly.

Thanks for this 👍

Hello, I have the same issue with RabbitMQ.

here is the error. i check the file and debug sinks are in there, but not RabbitMQ.
not sure if the Using is needed, but I tried many different ways, all come up with the same error.

Hi, the issue occurs because Serilog.Sinks.Logz.Io references core Serilog package indirectly via Serilog.Sinks.PeriodicBatching dependency. I've added fix for this in the incoming pr.
