Throw an ArkError programmatically

Is there an easy way to throw an ArkError programmatically without defining a schema?

I'd like to ensure a provided value is unique against my DB, so I'm looking for an alternative to this:

if (alreadyExists) {
  type({ url: type("true").configure({ message: "The URL already exists." }) }).assert(false)
}

if (alreadyExists) {
  type({ url: type("true").configure({ message: "The URL already exists." }) }).assert(false)
}

Ideally something simple like

throw new ArkError({ path: ['url'], message: 'The URL already exists." })

throw new ArkError({ path: ['url'], message: 'The URL already exists." })

For context, I'm using this in a tRPC procedure where I already validate the input to check if it's a valid URL.
