API receives posted metrics, but values are all zero

I have setup the graphite data source within my grafana cloud account. The data source tests successfully with “Data Source is working” message. I am using curl to send an api POST request to submit metrics and the command receives “Published” response. In the grafana explorer view, I can observe a data point on the graph for every published metric at the correct time that they were sent, but the value listed for every metric is 0. I have attempted to adjust the storage-schemas.conf intervals and the particular details of my posted metrics to no avail. I have recreated my graphite data source and continue to experience this issue.

#!/bin/bash

key=******************************************************************
addr="https://graphite-prod-10-prod-us-central-0.grafana.net/graphite"
timestamp_now_rounded=$(($(date +%s) / 10  * 10 ))
timestamp_prev_rounded=$((timestamp_now_rounded - 10))

metric="test"

curl -X POST -H "Authorization: Bearer $key" -H "Content-Type: application/json" "$addr/metrics" -d '[{
        "name": "telem.'$metric'",
        "metric": "telem.'$metric'",
        "interval": 10,
        "value:": 4.321,
        "time": '$timestamp_prev_rounded'
},
{
        "name": "telem.'$metric'",
        "metric": "telem.'$metric'",
        "interval": 10,
        "value:": 2,
        "time": '$timestamp_now_rounded'
}
]'

are you using Grafana Cloud?
