@troy,
I tried to install the snapshot several times but always end up with this error message in the homeassistant/blueprints/automation/truenas_api/zfs_snapshot.yaml.

Despite the error message, I have saved the file and tried to install the blueprint. It seems to work but it wrecks all of my automation, so much so the Automations label does not appear under Blueprints in the Configuration page. To restore the automations, I have to delete the entry in the automations.yaml and restart HA.
I am having the same issue with this: Fancy Home Assistant Update Available Notifier for Android (With customizable notification settings). The same error message appears and installing that blueprint also wrecks all automations. In that thread, @KTibow posted this:
It’s not an error, it’s just that the file editor inside of the addon is a more general one, and the syntax checker wasn’t updated for Home Assistant.quote
It is so odd I have consistent errors that no one else can replicate using the same code. This is what the automation looks like, what I am about to delete to ‘rescue’ my automations.
