Raycast Extension fetch error

While trying to use a custom Raycast extension that I built for work, it kept throwing a fetch error, something like this:
Turns out it doesn't like self signed certificates and uses some sort of default set of certificate authorities (CA).
It's a simple fix, and just requires a change to the Raycast Advanced Settings to set the Certificates to Keychain instead of Default:

As is often the case, the fix was found in the GitHub issues for raycast/extensions.
