UI index page suggest that “Please set a root dashboard for GENERAL”

[miracle-yyh]

I pulled the code for Skywalking 9.0, built the OAP and UI mirrors locally, and started them. Localhost: 8080 with a browser, the page appears normal, but something is missing. The page looks like this：

This problem has been bothering me all day, what should I do and how to set a root dashboard for GENERAL？

[wu-sheng]

All roots have been set in release. This means OAP is not working. Make sure you are using clean Database env.
Demo is using default dashboards, check showcase doc.

Thank you very much！
To some extent，it's true that OAP is not working: UI is failed to connect to the OAP.The real reson is that the SW_OAP_ADDRESS i
configured in starting command shouldn't be “http://127.0.0.1:12800” but the container ip.
And the oap-server/server-starter/src/main/resources/application.yml file seems to be missing the driverClassName configuration of mysql，after adding property and dependency，setting mysql as storage is working.

I have the same problem，I have read the upgrade documentation v9-version-upgrade，
ES delete ui_template,sw_service_traffic_xxxx,sw_instance_traffic_xxx

OAP is working

ui is working
env

SW_OAP_ADDRESS="http://sky-oap:12800"
SW_TIMEOUT="20000"

but ui page has not showing properly.

The easiest way is find a k8s, nd run showcase to demo, which is demo.skywalking.apache.org shows.

I don't have k8s, just run it locally. I have cleared all ES data and restart, still the same result.

I think sky-oap in your SW_OAP_ADDRESS can not be resolved,you could use docker/docker-compose.yml file in skywalking project to start oap and ui.
