Unable to scrape metrics using Victoriametrics VMServiceScrape

[jahnavisana2812]

Hello,

Our Grafana setup utilizes VictoriaMetrics, a Prometheus-compatible system. I'm currently attempting to scrape the metrics exposed on /service/metrics/prometheus, but encountering login issues resulting in a 500 error. Below, you'll find the configuration for the vmservicescrape component I'm using, along with the documentation I've referenced. Your prompt assistance would be greatly appreciated. Thank you.
