Hi, we are an ISP and we are thinking of migration from static RSVP tunnels to Segment Routing with an external controller. Our network is build mostly on Juniper MX devices, we cretead a lab with few routers and with an ODL Neon controller + Pathman-SR. Unfortunatelly we can't deploy any path.
So, what we have:
ODL Neon Controller
Pathman-SR
Juniper vMX devices running Junos 17.2R1.13

All the routers are seen in Pathman-SR, we have following topologies in our ODL controller:
example-linkstate-topology(all the routers/links are seen there)
example-pcep-topology(all the routers are connected to PCEP controller and session is UP, configured with Stateful, Active).
example-netconf-topology(the status is connected with all the routers)
I've attached a file, with the result of "/restconf/operational/network-topology:network-topology/"

When I try to deploy a path, I see the following error:
"Response indicated the error in frontend-backend communication."

This the error in karaf.log:

This is the log in /tmp/pathman.log:

This is the error which I see on Juniper MX in the log file of PCEP controller:

Can anybody advice what to do to solve the problem ?
Any help would be very appreciated!!!
