Struct: failed on block 2241767

[Ioannis Tsiokos]

Our backend that indexes block success rates for https://stakekilt.com, is running into an issue at block 2241767 (or the one after)

2022-10-05T06:19:34.554Z	889a5f14-3378-4e27-8703-23202096acac	ERROR	2022-10-05 06:19:34        RPC-CORE: getBlock(hash?: BlockHash): SignedBlock:: createType(SignedBlock):: Struct: failed on block: {
    "header": "Header",
    "extrinsics": "Vec<Extrinsic>"
}:: Struct: failed on extrinsics: Vec<Extrinsic>:: createType(ExtrinsicV4):: createType(Call):: findMetaCall: Unable to find Call with index [80, 4]/[80,4]

other indexers might face issues with it too, so maybe worth a look

all packages are up to date
"@kiltprotocol/type-definitions": "0.2.1",
"@polkadot/api": "9.4.3",
