Describe the bug

Fetching block by number is throwing the following error, the error can be reproduced using the following snippet:

The following works on ETH network but fails on Base.

let block = provider.get_block_by_number(BlockNumberOrTag::Number(block_number), BlockTransactionsKind::Full).await;
let block = match block {
    Ok(block) => block,
    Err(err) => {
        println!("{:#?}", err);
        return;
    }
};

println!("{:#?}", block);

Result:

DeserError {
    err: Error("data did not match any variant of untagged enum BlockTransactions", line: 1, column: 189508),

are you using the AnyNetwork or Ethereum, for optimism you'd need the AnyNetwork or Optimism https://github.com/alloy-rs/op-alloy

[hjawhar]

I believe I was using Ethereum by default:

let provider = ProviderBuilder::new().on_http(rpc_url);

[mattsse]

yeah this would fail for the deposit tx type on block level, which is not supported by the ethereum network impl
