@husofskyzy Hi, I'm from the Apache HugeGraph(incubator) team, and we are currently encountering a codecov issue, Can I ask some questions?

After we migrated the hugegraph project to apache, codecov could not send the report to the github PR. It seems OK for linkis PR, what operations you have done? Do you installed the codecov app for linkis repository? Thanks~

Thank you.
We also update .github/workflows/ci.yml, but codecov still could not send the report to the github PR. Do you mean the codecov app is installed in github settings/installations location https://github.com/apache/incubator-linkis/settings/installations ?
