Check URL if it Exists or for a Specific Status Code on Custom Link

[cyberndj]

Howdy,

We are using Azure Dev Ops to store our network configurations/backups based on the devices name.
I am able to create a custom link that points to the correct path for each device based on the name (ex https://my.dev.azure.com/repository/Config_backups/{{object.name}}.cfg ) and the link works as expected.

I would like to hide the link for devices (like patch panels) if they 1) don't have any configurations stored or 2) have a device role in "Access Switch, Distribution Switch, Router, Core Switch" etc.

I know I can create a custom field with the exact URL, and create an if statement on the link like below, but I would like to keep it dynamic.

I did find a test URL https://dev.azure.com//Items?path=/Config_backups/{{object.name}}.cfg&recursionLevel=0&includeContentMetadata=true&versionDescriptor.versionOptions=0&versionDescriptor.versionType=0&versionDescriptor.version=main&includeContent=true&resolveLfs=true that returns a 404 if it doesn't exist and a 200 if it does.

If a url check is not possible, how can I set the link to only show if the device role is apart of Access Switch, Router, Distribution Switch, etc?

{% if object.cf.secretserver is not none %}
View Passwords in SecretServer 
{% endif %}

Thanks!
