java - Sawtooth 1.1.2 添加区 block 到创世区 block 时获取 'rejected due to invalid predecessor'

Question

我无法向链添加新 block ，因为锯齿 validator 默认正在报告:[2019-01-25 18:18:54.029 警告 block_validator] 区 block 7f3...370e(block_num:1，state:c3a...954，previous_block_id:0d8...09d)验证失败:区 block 7f3。 ..370e (block_num:1, state:c3a...954, previous_block_id:0d8...09d) 由于前驱无效 0d8...09d (block_num:0, state:66e...ee1, previous_block_id:0000000000000000 而被拒绝)

我猜这是一个时间问题，因为它刚刚开始发生，并且在同事的环境中仍然可以正常工作。

今天早上我尝试运行以下操作序列 7 次:

1. docker-compose 下来
2. gradle clean 构建 fatJar docker
3. docker-compose up --build
4. GET localhost:8008/blocks --> 1 个区 block 如预期
5. 将 locApplication 发布到链
6. GET localhost:8008/blocks --> 显示已添加的 block ...或未添加
7. 获取本地主机:20005/api/v1/lettersofcredit/applications/?id=d26...f2d

有效吗？ Y|N|N|Y|Y|Y|N

我没有看到来自 settings_tp 的任何输出，仅来自默认 validator 。每次新的区 block 提交都会返回202 ACCEPTED。

我正在开发人员模式下运行，使用 docker-compose 在单个 Ubuntu 18.0.4 VM 上运行所有容器。这是 docker-compose.yaml:

任何有关我如何调试此问题的建议将不胜感激。谢谢。

要在 Developer Mod 中使用，您应该安装并运行 DevMod 共识。
安装

sudo apt-get install sawtooth-devmode-engine-rust   

启动 validator 后，在另一个终端开始共识

sudo -u sawtooth devmode-engine-rust -vv --connect tcp://localhost:5050
