Hello, when I git clone the newest code , and then

prefect dev start

, I found that the UI is blank

Hi Howard, what are the steps you performed to get to here? We don’t natively expose on :3000, so I suspect there is something else going on

prefect dev start

will run the UI on port 3000 and the Orion API on port 4200, but it looks like perhaps Orion didn't start and as a result, the UI isn't able to communicate with it. I'd begin by running

prefect orion start

to run a standalone Orion server. That will make it easy to see any errors that are preventing the API from starting up.

Ah, my mistake - thanks Ryan

Actually Orion API was started. And I can't access http://10.41.6.40:4200/api/helath and http://10.41.6.40:4200/ui-settings. I want to use the hot reloading feature of development, but if it can't be used, I'll try to use

prefect orion start

, thank you all!

if the ui is blank..you should build the orion-ui first. follow the steps in orion-ui/readme
