Describe the bug

Node provider is Reth. Here is the code that encountred this bug:

use alloy_network::Ethereum;
use alloy_provider::{
    layers::{CacheLayer, CacheProvider},
    RootProvider,
};
use alloy_pubsub::PubSubFrontend;

pub use alloy_provider::Provider;

pub type NodeProvider = RootProvider<PubSubFrontend, Ethereum>;
pub type CacheNodeProvider = CacheProvider<NodeProvider, PubSubFrontend, Ethereum>;

pub fn create_cache_provider(
    provider: NodeProvider,
    cache_provider_limit: u32,
) -> CacheNodeProvider {
    let cache_layer = CacheLayer::new(cache_provider_limit);

    CacheNodeProvider::new(provider, cache_layer.cache())
}

#[cfg(test)]
mod test {
    use alloy_primitives::address;
    use alloy_provider::{Provider, ProviderBuilder, WsConnect};
    use anyhow::Result;

    use crate::node_provider::create_cache_provider;

    #[tokio::test]
    async fn should_get_nonce() -> Result<()> {
        let ws = todo!("add node ws");

        let provider = ProviderBuilder::new().on_ws(WsConnect::new(ws)).await?;

        let cache_provider = create_cache_provider(provider, 2000);

        let weth_address = address!("c02aaa39b223fe8d0a0e5c4f27ead9083c756cc2");

        cache_provider.get_transaction_count(weth_address).await?;
        // Error: deserialization error: invalid type: string "0x1", expected u64 at line 1 column 5

        Ok(())
    }
}

@yash-atreya I believe this is an issue with deserialization here

because this is picking the return type u64

alloy/crates/provider/src/layers/cache.rs

Line 132 in 79facc2

if let Ok(Some(cached)) = $cache.get_deserialized(&hash) {

but we stored U64
