Errors & Limits

TL;DR

• HTTP側制限（body/batch/depth）とRPC側制限（blockTag/filter/range）の二層で制御。
• エラーコードは -32602/-32000/-32001/-32005 が中心。

Gateway HTTP制限

• RPC_GATEWAY_MAX_HTTP_BODY_SIZE
• RPC_GATEWAY_MAX_BATCH_LEN
• RPC_GATEWAY_MAX_JSON_DEPTH

RPCエラー

• -32602 invalid params
• -32000 state unavailable / execution failed
• -32001 resource not found
• -32005 limit exceeded
