I changed the value of this to ContractClass:

RawJson(Cairo0Json), Rpc(ContractClass),

And i can handle it better than changing the value of the Rawjson. But i have errors with the changes i made. Is not clear to me which one i have to change.

the idea is to change the value of RawJson variant from Cairo0Json to starknet_api::deprecated_contract_class::ContractClass. Then rename the variant from RawJson to StarknetApi
