Fresh Example Fails to Build + deno.lock version 4 unsupported

[A1029384756]

Was looking at using this to package a Fresh website I wrote. Initially I attempted to package it via the example flake. Once that failed, I tried the example but got a hash error on a dependency.

After updating the lockfile using the latest version of Deno (2.1.4 at this time) I saw that npm would have issues because of Deno changing to lockfile v4. To get around this, I updated the source with:

(if denoLock.version == 3 then denoLock.packages.npm or { } else if denoLock.version == 4 then denoLock.npm or { } else throw "unsupported lockfile version")

After doing this, the npm deps worked, but I get this error:

When looking in the generated lockfile however, this is listed under remotes and I also see this in the nix store:
/nix/store/ikbva52xykkwfnrfny0icy2da762qhhd-deno.land-std-0.208.0-dotenv-load.ts

Is there anything I am missing?

As additional info, this issue also seems to be present on the remote example.
