Before I forget, I updated the Ktor Client yesterday, which I’m using in Javascript, and ran into an issue where it was always outputting ContentNegotation related trace logs to “console.info”. Looking under the hood, it appeared it always used a global logger, and was completely unaffected by changing the logger in the Logging {} configuration for the client. This broke something for me because I was using the client as the backend of a CLI tool that depends on outputting JSON, and suddenly it wasn’t working-as-intended!

Here is the issue https://youtrack.jetbrains.com/issue/KTOR-5456

excellent! thanks Aleksei
