Kong Manager not loading data in DB less mode

Enabled Kong Manager in the Kubernates , and I am accessible Kong Manage UI through Ingress URL.
But when I click any resource its showing below error.
Data cannot be displayed due to an error.

Can we use Kong Manager In DB less Mode or not?
Can we use Kong Manager in for Kong Community version?

Hello, do Default Kong manager missing settings to API · Kong/kong-manager · Discussion #99 · GitHub and The file manifest for Kong OSS on K8S with the Kong Manager OSS does not exist · Kong/kong-manager · Discussion #73 · GitHub help? If not, could you open the “network” tab in the browser devtool to see what is the error?
