Mirroring not working with dynamic Juniper header disabled

[Shashikiran H]

Version: 3.1.0.0-6 kilo

Topo:
cfgm: nodec22
control: nodec22,nodec26,nodeg10
compute: nodeg8,nodeg14,nodec15 and nodec11

source vm is 100.1.1.4, receiver is 200.1.1.3, mirror is in sender VN, it is 100.1.1.3

I have disabled the Juniper header:
        "virtual_machine_interface_properties": {
            "interface_mirror": {
                "mirror_to": {
                    "analyzer_ip_address": "100.1.1.3",
                    "analyzer_mac_address": "2:d1:80:5:dc:6e",
                    "analyzer_name": "left-to-right",
                    "juniper_header": false,
                    "nh_mode": "dynamic",
                    "routing_instance": "default-domain:demo:sender:sender",
                    "static_nh_header": null,
                    "udp_port": 200
                },
                "traffic_direction": "both"
            },
            "local_preference": null
        },

The packets reach the fabric, but do not get mirrored to analyser vm.

I had both VN and port mirror enabled here. If there is a VN based mirroring enabled on top of the port mirroring, the packet does not take the flow entry created for mirror. Since the flow for mirror is not hit, packets are not mirrored. Removing the VN based mirroring and having only port mirroring worked and the packets were mirrored without header properly.
