@nic-6443 Because the frontend static files are not compiled and correctly placed during the backend E2E test, the server will respond to 404 errors. Just ignore it.

@nic-6443 I have fixed this problem.
By the way, have you tested the effect of gzip compression on speeding up the transmission of static resources in your local environment?

Yes, static files size decrease greatly after gzip.

According to the maximum file size (~500k) and 5s timeout, then the network transmission speed is greater than 100 KB/s, it can work normally.
