Wrong IP in span attribute client.address

[pirm-in]

We have configured forwarded_by_client_ip and trusted_proxies in the router settings, and the correct client IP shows in the access logs, e.g. 167.94.x.x. But i just noticed, that the client.address span attribute has the IP address of the latest proxy.

Example

label	value
client.address	"10.254.0.4:43550"
krakend.stage	"global"
server.address	"my.tld.com"

Also i couldn't find the client.address span attribute in the docs.
