Description

According to the output on Devnet, error_message:"Interpreter error: host module doesn't export function with name casper_add_contract_version",
whilst the same deploy process with the same contract on Tesnet has been successful, it is likely that updating our smart contract will be required.

Would that be true? If so, where should I look for the related information besides this, casper-contract-4.0.0 > Function casper_contract::contract_api::storage::add_contract_version ?

Note that storage::add_contract_version(contract_package_hash, entry_points, Default::default()); is used in our source code.

If you could provide us tips on this, that would be appreciated.

The arguments for that host function have changed. This is how it looks now

pub fn add_contract_version(
    package_hash: PackageHash,
    entry_points: EntryPoints,
    named_keys: NamedKeys,
    message_topics: BTreeMap<String, MessageTopicOperation>,
) -> (AddressableEntityHash, EntityVersion)

So the error does make sense. For more details please refer to casper-node.
An example of usage in cep-18

Hi @na-OKADA can you update if it works now

[na-OKADA]

Hi @cspramit Unfortunately, it still keeps failing, https://devnet.make.services/deploys/3457da646f4d925ff1c2e669937b1e80e09b26c64c3e94e54a9cfb1f337adc5b.

In the next internal meeting, the contract developer may be able to help. In the meanwhile, if you have any other tips on that, please let me know.

Hi,
error_message:"Wasm preprocessing error: Deserialization error: Invalid table reference (128)"

Where am I supposed to modify to solve this error which I encountered in deploying our smart contract on to Devnet, https://devnet.make.services/deploys/194988146d2e9beea5a0ad16245dbb15fa34d2ad5837f27192cbb280c38761a3?

Can we still use amount: i64 ?

If you need to look through our code, please let us share in private such as email. @devendran-m

Hi, one of our developers helped to modify our smart contract code and it is successfully deployed on to Devnet, here though, we are looking for a way to obtain its contract hash.

According to this, it looks like that "contract hash" has been deprecated....

Can you help on that?
