[Bug]: nix bad illegal url error after auto upgrading to 0.5.0

[tclain]

Current Behavior (bug)
Since auto upgrade to 0.5.0, I get the following message when activating devbox in my production repo:

direnv: loading ~/z/next/.envrc
direnv: using devbox
direnv: using nix .devbox/gen/shell.nix
error: unable to download 'github:NixOS/nixpkgs/f80ac848e3d6f0c12c52758c0f25c10c97ca3b62': URL using bad/illegal format or missing URL (3)

       … while realising the context of a path

       at /Users/tclain/z/next/.devbox/gen/shell.nix:2:10:

Expected Behavior (fix)
No errors should happened

Additional context

• fish shell

Please include the output of devbox version -v and
0.5.0
a copy of your devbox.json file.

Hey @tclain , thanks for reporting. Looks like a pretty serious issue, so we'll take a look and try to resolve ASAP

If you need to unblock yourself, you can export DEVBOX_USE_VERSION=0.4.9 to revert to the 0.4.9 version of Devbox. Once we resolve the issue, you can unset the variable to revert to the latest version.

One quick request, can you run nix --version and share the output?

@Lagoja

(devbox) ◆  ❯❯❯ nix --version
nix (Nix) 2.11.1

sorry for the wait, twas nitght time :-)

@tclain we're working on a fix for this. This was caused because we made changes to our envrc file generation and how we handle direnv. The fix will be in the next release.
To prevent an issue like this happening for you, I recommend doing the following:

1. make a backup of your .envrc file cp .envrc .oldenvrc
2. regenerate .envrc by running devbox generate direnv --force

This will create a new .envrc file which is less likely to cause backwards compatibility bugs.
