I m having some issues with the Java Client We have followed

Question

I m having some issues with the Java Client We have followed the deployment setup outlined <https docs cerbos dev cerbos latest deployment k8s sidecar html|here> to deploy Cerbos as a k8s sidecar Instead of the ghostunnel application we have a spring boot API that is using the Java client We use the following code to iniatlize the client ```final CerbosBlockingClient cerbosClient = new CerbosClientBuilder unix sock cerbos sock withPlaintext buildBlockingClient ``` The client is created without error but once we try to issue an API call we get the following error in our logs ```nested exception is dev cerbos sdk CerbosException RPC exception Status code=UNAVAILABLE description=io exception cause=io grpc netty shaded io netty channel AbstractChannel$AnnotatedConnectException connect failed Address family not supported by protocol sock cerbos soc``` Not sure if we are specifying the unix socket correctly in this example and struggling to find examples online that do this

If it helps here is the full stacktrace ```Caused by java net ConnectException connect failed Address family not supported by protocol at io grpc netty shaded io netty channel unix Errors

Hi try with `unix sock cerbos sock`

Jay StGelais · Answer

I have tried with the 3 slashes as well and get the same error

Jay StGelais · Answer

Let me try again though in case I might have mistypesd something the last time

Charith (Cerbos) · Answer

Oh it could be because `grpc java` doesn t support Unix domain sockets <https github com grpc grpc java issues 1539> Perhaps try with TCP If you are using a side car you can make Cerbos listen on 127 0 0 1 only so it won t be accessible from the outside anyway

Jay StGelais · Answer

That s good to know We ll go that route

Alright Got further but now it looks like I m hitting an issue that is probably my own doing but unfortunately the error being logged is rather opaque ```dev cerbos sdk CerbosException RPC exception Status code=INTERNAL description=Resources query plan request failed cause=null with root cause dev cerbos sdk CerbosException RPC exception Status code=INTERNAL description=Resources query plan request failed cause=null at dev cerbos sdk CerbosBlockingClient plan CerbosBlockingClient java 149 ~ cerbos sdk java v0 5 0 jar na ``` Is there a way to turn request logging on for the client to capture the post bodies

Jay StGelais · Answer

nevermind found the error in the cerbos log
