Incorrect Content-Length - when using a custom api router after ssl enabled gateway

[abwl084]

Routing works fine when gateway is not ssl enabled. After enabling ssl with a self signed cert I get this error:

2025-02-26 21:26:42 2025-02-26T19:26:42.734Z ERROR http-worker-70 io.trino.gateway.ha.router.ExternalRoutingGroupSelector Error occurred while retrieving routing group from external routing rules processing at https://host.docker.internal:8000/gateway

I am able to call the my custom api from the gateway container with full ssl validation.
