Unable to connect to ditto nignx

[sheeperyang]

Hello, I followed the tutorial on the official website to set up a cluster using minikube and deployed the openTwins platform. Currently, all pods are in running mode, and Grafana can access, log in, and configure openTwins through browser policies. But when creating the digital twin, I couldn't find any available policies, including basic_policy.
I tried to create a policy using the ditto Nginx API as mentioned in other isues, but after logging in to ditto Nginx using a browser, all interfaces except for the initial interface could not be accessed properly (404).
Regarding this inconvenience, I would like to seek your advice. Is this a normal phenomenon? Is this due to communication issues or installation problems?
I have checked the logs and it seems that the lack of an HTML file is causing the interface to not display?
If you could reply, I would greatly appreciate it!

When deploying openTwins, some pods were unable to run properly, so I used kubectl delete podto restart the pods. Will this operation cause any problems?

I tried installing with the sudo command, but encountered an incomprehensible error?
