aliyun-exporter使用时出现错误

我根据https://help.aliyun.com/document_detail/28619.html?spm=a2c4g.11186623.6.670.4cb92ea7URJUmT 添加了
acs_polardb:

启动容器发现 错误

During handling of the above exception, another exception occurred:

----------------------------------------

No repository file, test, or entry point is named; the report only provides the Aliyun documentation link, an acs_polardb configuration, and a Python traceback. First reproduce the container startup with that configuration and determine whether the failure belongs to kubectl-debug or another exporter. Done means identifying the correct project and providing a minimal reproduction or a confirmed fix location.
