Failing when customPricing set

[mogaal]

Using the latest version of the Helm Chart (version: 1.37.0) and setting customPricing to true (.Values.opencost.customPricing.enabled) cause the pod to fail with the following error:

The configMap gets mounted as a file on /tmp/custom-config (not directory) as you see below

~ $ ls /tmp/custom-config -l
-rw-r--r--    1 root     root           299 May 15 10:27 /tmp/custom-config
~ $ cat /tmp/custom-config 
{
  "CPU": "1.25",
  "GPU": "0.95",
  "RAM": "0.5",
  "description": "Modified pricing configuration.",
  "internetNetworkEgress": "0.12",
  "regionNetworkEgress": "0.01",
  "spotCPU": "0.006655",
  "spotRAM": "0.000892",
  "storage": "0.25",
  "zoneNetworkEgress": "0.01",
  "provider" : "custom"
}~ $

It should be instead mounted as /tmp/custom-config/default.json. A fix would be removing the subPath (so it gets mounted as directory) in this line.

Helm values file used for the tests:

opencost:
  customPricing:
    enabled: true
