Hi all,

I can’t find the reason why this middleware isn’t being detected. Even the DEBUG log doesn’t show me any additional information. Can someone give me a hint?

Here’s the error message from the log:  
2024-10-31T16:06:36+01:00 ERR error="middleware "cloudflarewarp@file" does not exist" entryPointName=http routerName=http-to-https@internal

If I completely remove Cloudflare Warp, then it can’t find CrowdSec anymore...

Is is finding CrowdSec, when it does not find Cloudflare Warp?
