Stuck at start metabase

Hi
When I start Metabase, I am stuck at Initializing task SyncDatabases. And I access localhost:3000, it shows me the guide page, not the index page.
branch: release-x.37.x
Who can help me? Thanks in advance.

Hi @caidaoliuhai
What is “guide page”?
Which changes have you made?
I would recommend building based on tags like v0.37.5, since that’s a release, whereas branches might have work-in-progress.
And you can try enabling debug/trace logging to figure out what’s causing the stall at the sync task:

Thank you. I reclone Metabase and change it to v0.37.5 tag. Then start successfully.
