Get SAI_OBJECT_TYPE_FDB_ENTRY failed by npu.process_commands

[xuyinhao]

my simple code :

    idx=0
    mac = macs[0]
    cmds3 = [
       {
            "name": f"fdb_{idx}",
            "op": "get",

                "mac_address": mac,
                "switch_id" : "$SWITCH_ID"
            },
            "attributes": [
                "SAI_FDB_ENTRY_ATTR_TYPE"
            ]
        }
    ]
    status = [*npu.process_commands(cmds3)]
