[ERROR publish_creation] <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726)>
用例
在 Houdini 17.5 中开发数字资产工具时，我使用构建工具包应用执行一个挂钩，尝试注册已发布的文件。
该脚本将执行代码：
args = {
"tk": self.parent.tank,
"context": self.parent.engine.context,
"path": esto['operator'],
"name": os.path.basename(esto['operator']),
"version_number": 6,
"published_file_type": "Library item",
}
print 'sgtk: ', sgtk.__file__
sg_publish = sgtk.util.register_publish(**args)
已发布的文件已在 ShotGrid 中正确注册，但显示以下错误：
