Tezos RPCは、現在のチェックポイントより下のブロックで応答しません

Tezosノードの独自のインスタンスを実行しましたが、ノードが現在のチェックポイントより下のブロックで応答しないようです.

GET /chains/main/checkpoint応答:

 {
  "block": {
    "level": 212993,
    "proto": 3,
    "predecessor": "BLMXXvPj4rfPinsTcwgQkws5iqcqZKLnxCrSHXYErRk8Yt8s4ui",
    "timestamp": "2018-12-04T01:25:03Z",
    "validation_pass": 4,
    "operations_hash": "LLob1oFfM5pLnSH8vi9kM57JH9toqS9jR6XGkZt9gHeqzKiusBpge",
    "fitness": [
      "00",
      "000000000061a690"
    ],
    "context": "CoUu7Z1PCS3FoQqN96UAczb25S9c5HCtPsNbuQXdeT2CNqsssbaG",
    "protocol_data": "000100000003ddfe5afc00ed6f3c49c78ed62ff003b09b5af7db2b0479b79367cb60c2a1a85caeae20fca4da576f19ce9116a2cd6eafc1d737d032aa9ed1e3b292b57d378bd0ff90acf505"
  },
  "save_point": 212993,
  "caboose": 0,
  "history_mode": "full"
}
 

つまり、ご覧のとおり、history_modeは「フル」です.この記事によると https://blog.nomadic -labs.com/introducing-snapshots-and-history-modes-for-the-tezos-node.html このモードのノードはすべてのブロックを保存します.

しかし、 GET /chains/main/blocks/212992の応答は404Not Found、 ただし、

GET /chains/main/blocks/212992/header応答はブロックヘッダーです.

GET /chains/main/blocks/212993は正しく機能し、期待どおりにブロックに応答します.

dockerイメージを使用してノードをデプロイしました.

UPD :GET /chains/main/blocks/212992/operationsも機能しません

I've run my own instance of Tezos node and it seems that the node doesn't respond with blocks below the current checkpoint.

GET /chains/main/checkpoint response:

{
  "block": {
    "level": 212993,
    "proto": 3,
    "predecessor": "BLMXXvPj4rfPinsTcwgQkws5iqcqZKLnxCrSHXYErRk8Yt8s4ui",
    "timestamp": "2018-12-04T01:25:03Z",
    "validation_pass": 4,
    "operations_hash": "LLob1oFfM5pLnSH8vi9kM57JH9toqS9jR6XGkZt9gHeqzKiusBpge",
    "fitness": [
      "00",
      "000000000061a690"
    ],
    "context": "CoUu7Z1PCS3FoQqN96UAczb25S9c5HCtPsNbuQXdeT2CNqsssbaG",
    "protocol_data": "000100000003ddfe5afc00ed6f3c49c78ed62ff003b09b5af7db2b0479b79367cb60c2a1a85caeae20fca4da576f19ce9116a2cd6eafc1d737d032aa9ed1e3b292b57d378bd0ff90acf505"
  },
  "save_point": 212993,
  "caboose": 0,
  "history_mode": "full"
}

So, as we can see history_mode is "full". According to this article https://blog.nomadic-labs.com/introducing-snapshots-and-history-modes-for-the-tezos-node.html node with this mode stores all blocks.

But, GET /chains/main/blocks/212992 response is 404 Not Found, however,

GET /chains/main/blocks/212992/header response is a block header.

GET /chains/main/blocks/212993 works properly and responses a block as it expected.

I used docker image to deploy the node.

UPD: GET /chains/main/blocks/212992/operations also doesn't work
