This issue is seen due to incorrect configuration where interface family is "inet" whereas forwarding-options port-mirroring is configured with family inet6.

After fixing the config, no more error is observed.

Ex:

set interfaces gr-0/0/0 unit 0 family inet address 192.168.50.1/30
set forwarding-options port-mirroring family inet6 output interface gr-0/0/0

To fix this issue, configured family inet6 for the interface:

set interfaces gr-0/0/0 unit 0 family inet6 address 2a0b:5f00:0:1::49/127

This error is expected due to enhancement in PR 1729028 which will throw error for invalid CLI.
