Cant retrieve metrics from Kubernetes kind's

[mustafataskir-bcfm]

I have a Kubernetes cluster installed on AWS EKS version 1.25. I installed krr on my local computer with brew. I am publishing the Prometheus service with port forwarding, and while krr reports that it is connected, I am receiving the following errors.

krr simple -n monitoring --history_duration 10

Calculating Recommendation |████████████████████████████████████████| 6 in 3.7s (1.02/s)

The values in the table also appear as 'unset'.

Where am I making a mistake?

Additionally, when I scan a namespace with defined request-limit, it shows the existing resource values but does not provide any recommendations. I am receiving the same warning logs.
