@s4rv4d
try running this

use dep::std;

fn main(
hashed_message : [u8;32],
pub_key_x : [u8;32],
pub_key_y : [u8;32],
signature : [u8;64],
) {
let valid_signature = std::ecdsa_secp256k1::verify_signature(pub_key_x, pub_key_y, signature, hashed_message);
assert(valid_signature);
}

It is a poor solution, but you can also downgrade noir to version 1.0.0-beta.3 then remember to run bbup to update backend to compatible version as well if you are using it ofc.

yes.. forgot to mention the downgrade alternative!

for anyone that comes here - the fix has been merged into https://github.com/colinnielsen/noir-array-helpers/releases/tag/v0.30.1 , but this repo hasn't been updated to use it yet

manually going into your nargo cache file and updating the version fixes it until the update is merged

// in ~/nargo/github.com/colinnielsen/ecrecover-noir update the version to v0.30.1 or higher:

array_helpers = { tag = "v0.30.2", git = "https://github.com/colinnielsen/noir-array-helpers" }

[dependencies]
array_helpers = { tag = "v0.30.2", git = "https://github.com/colinnielsen/noir-array-helpers" }
ecrecover = { tag = "v1.0.0", git = "https://github.com/colinnielsen/ecrecover-noir" }

This is what I have in my Nargo.toml file, and I still have the error. I'm not sure of what I'm doing wrong.

@Princeigwe - you need to update the version of the array_helpers dependency within your local installation of nargo. Ecrecover is preinstalled there, and the version of array_helpers is set to 0.30.0 as a default within the nargo.toml.

Once you change the version there and save, you can remove ecrecover from your local project's nargo.toml and then be good to go.
