Hi! Using ktor 1.5.2. I'm getting these Netty exceptions in the logs:

java.lang.IllegalArgumentException: text is empty (possibly HTTP/0.9)

The requests are made using Chrome (so it's not HTTP/0.9 for sure). It seems even I get the exceptions the requests are received. Any ideas?

Hi! Did you have it before 1.5.2?

I don't think so... but I'm getting these errors after a huge update to the service (upgrading many dependencies and server code). The errors are not showing in the tests.
