Can you try the below code?

abigen!(
     DAI,
     "etherscan:0x6b175474e89094c44da98b954eedeac495271d0f"

Same error. Any features wrong?

I believe this is related to this commit: d53ca0e cc @mattsse.

We're hitting the Err case here when we shouldn't be:

 cfg_if! {
        if #[cfg(any(not(target_arch = "wasm32"), not(features = "reqwest")))]{
            Err(anyhow!("HTTP is unsupported"))
        } else {
            Ok(reqwest::blocking::get(_url)?.text()?)
        }
    }

Fixed in #632
