Decoding Metadata with subxt-metadata about acala HOT 5 CLOSED

That will be due to

and the concrete type of ConvertEthTx is

It is a helper type and should not have impacts to metadata

I will still say it is subxt bug to not ignore it

from acala.

it is mostly likely subxt issue. could you provide a reproducible example?

@xlc Hi, please find a minimum reproduction here: https://github.com/trevor-crypto/acala-repro/blob/master/src/main.rs

I stored the metadata in a file called metadata.txt. It is take directly from this node - https://acala-rpc.dwellir.com/ - using the RPC call that I mentioned above.

Many other chains are working using the same method, so just wondering if there is something unique in the Acala metadata that is breaking decoding.

After adding a dbg! to the subxt_metadata crate:

        metadata.map_err(|_e| {
            dbg!(_e);
            "Cannot try_into() to Metadata.".into()
        })

I can see the error!

_e = TypeNameNotFound(
    "ConvertEthTx",
)

Which is defined in the metadata as:

{
  name: ConvertEthTx
  type: null
}

@xlc what's the purpose of this if it's just null?

from acala.

@xlc Thanks! I will close this and continue the investigation and fix here
