[htynkn]

there is no codecov change recently and also I can confirm codecov data is updated, for example:
https://codecov.io/gh/apache/dubbo/pulls

I also double check some of apache project:
https://github.com/apache/shardingsphere-elasticjob/pull/1542

codecov comment not showing too. so I guess it maybe some infra issue from codecov.
will follow up.

works now without any change in dubbo repo
