I have read https://ktor.io/advanced/pipeline.html but I am still a bit lost when it comes to how to control exactly when a Feature is run. I have a feature that should be run after authentication (I want to check if a principal is present) but before it is too late to make a

call.respond(...)

. It seems that whenever I insert my feature to a

PipelinePhase

it is either too early for the principal to have been processed (I can see for example that the

Authorization

header is present, but

principal

is null because it has not been set yet) or to late to make a response to the request. How do I solve this (in a good manner)?
