Can you load /e/home in your browser?

[rickywu]

First login I can load /e/home, but failed after config git repo, I think this because I deploy wiki in internal server without internet access

This problem happen init db in MySQL 8.0 and the UI seems not render correct:

I tried init db in MySQL 5.7 and import to 8.0 can fix this problem.

Also I verified this problem only happen in docker, If I install mannually and run node server works well.
