Node Exporter not showing up due to config.yaml schema validation error (list?)

[valentine0310]

Hello,

I am unable to see or install the Prometheus Node Exporter add-on after adding your repository (https://github.com/racksync/hass-addons-suite) to my Home Assistant Add-on Store. I was using this add-on successfully until about a week ago.

When I try to re-add the repository, the Home Assistant Supervisor log shows a schema validation failure for the Node Exporter's configuration file. It appears the issue is with how certain schema fields are defined, which is preventing the add-on from being recognized by the Supervisor.

Below are the relevant error messages from the Supervisor log:

It doesn't seem to like the way these options are defined:

  custom_collectors: list?
  ignore_mount_points: list?
  ignore_network_devices: list?

Reverting this commit 8646134 made it work again on my forked repo https://github.com/L4R5/hass-addons-suite

This does not really allow configuration for

  custom_collectors: list?
  ignore_mount_points: list?
  ignore_network_devices: list?

But at least it starts the exporter after disabling protection mode.
