Has testing (or routing) changed drastically between ktor 1.0.0 and 1.1.2?
I migrated my routes to extension functions to separate them into files and in 1.0.0 they pass just fine, but once I bump up the version to 1.1.2 the responses become null all of a sudden.
Edit: 1.1.1 works just fine, 1.1.2 can't seem to read the content of ApplicationCall
Edit 2: Might be something wrong with content negotiation as the status just before it returns null is 415
