I have PUT a NETCONF device (Junos vMX r18.2) on ODL (Magnesium stable version) using the following Postman command

PUT http://<MY_CONTROLLER>:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/VMX-1

The device is created ok and I can query the config and operational state

GET http://<MY_CONTROLLER>:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/VMX-1/

However, when I attempt to retrieve all its capabilities which are available through the mount point using ...

http://<MY_CONTROLLER>:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/VMX-1/yang-ext:mount

I receive the following reply

{
    "errors": {
        "error": [

{ "error-type": "application", "error-tag": "operation-failed", "error-message": "NETCONF operation failed" }

]
}
}
Looking at the controller log I see exceptions ...

My controller is installed on Cento7 and build with java11

I'm following instructions given in the cookbook
https://subscription.packtpub.com/book/virtualization_and_cloud/9781786462305/1/ch01lvl1sec11/mounting-a-netconf-device

Is this an issue with what the device is returning ? I can see on the device log its returning the full configuration, but the ODL is failing to read it
I've tried various release of ODL
