Error when searching with nixpkgs extension

[Damnjelly]

When using the nixpkgs extension, regardless of input, the following error is shown:

command failed: error: Uncaught (in promise) Error: Failed to search: Not Found
    if (!response.ok) throw new Error("Failed to search: " + response.statusText);
                            ^

I'm using the sunbeam 1.0.0 binary packaged with sunbeam-linux_amd64.tar.gz
