Debug Output

tofu "state show module.tech_dev_cn_hongkong.alicloud_mongodb_instance.masked"

# module.tech_dev_cn_hongkong.alicloud_mongodb_instance.masked:

    replica_sets                = [

            vswitch_id            = "vsw-masked"
        },
    ]
...
}

Expected Behavior

Suppose replica_sets is an array should return both primary and secondary connection object
But replica_sets now only returning a single object randomly, sometime is secondary, sometime is primary

Actual Behavior

replica_sets should return both secondary and primary connection object
