Jenkins 环境：

Jenkins ver. 2.164.2
Allure Jenkins plugin: 2.28.1

项目配置：

构建:
执行 shell：
python3 -m pytest -q test_sample.py --alluredir ${WORKSPACE}/allure-results
构建后操作：
Allure Report:
Results path: ${WORKSPACE}/allure-results
其它配置保持默认。

问题：

1. 在项目中点击 Allure Report，提示：HTTP ERROR 404
   
   

2. 执行构建后失败：
