`nh search` error decoding response body

[elaijuh]

my env is detsys + nix-darwin + flake, nh is install in system packages i observed nh version is a little bit weird, i can see the version 4.1.2 in /nix/store but it actually shows 4.1.1

$ nh --version
nh 4.1.1

$ ls -l $(which nh)
lrwxr-xr-x  1 root  wheel  59 Jan  1  1970 /run/current-system/sw/bin/nh -> /nix/store/ddryjzbjsfksgzxxw5mvm3hb55axk3fq-nh-4.1.2/bin/nh

$ /nix/store/ddryjzbjsfksgzxxw5mvm3hb55axk3fq-nh-4.1.2/bin/nh --version
nh 4.1.1

run nh search fastfetch -v i see below output.

Cannot reproduce on mainline Nix.

i am using nixpkgs.url = "github:nixos/nixpkgs/nixos-25.05", x86_64-darwin

It's failing on a 400 error. Make sure you can connect to search.nixos.org.

[NotAShelf]

I've improved the error behavior in recent commits. Please see if the error persists with nh built from the master branch, and provide the new --verbose output if it does.

i am sure it's connectable. but seems /backend/latest-43-nixos-unstable/_search needs auth

[NotAShelf]

NH establishes the authenticated connection during search.

NH establishes the authenticated connection during search.

from the debug log, username: "" and password: None.

req=Request { method: POST, url: Url { scheme: "https", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("search.nixos.org")), port: None, path: "/backend/latest-43-nixos-unstable/_search", query: None, fragment: None }, headers: {"content-type": "application/json", "user-agent": "nh/4.1.1", "authorization": Sensitive} }

[NotAShelf]

See the relevant bit for auth handling.

Though I doubt that is the issue. From your logs:

Something is intercepting your connection.

Something is intercepting your connection.

i have a http_proxy yes

[NotAShelf]

The log message reads off like your proxy is redirecting the search endpoint to an invalid access. Please see if the command succeeds without the proxy enabled.
