Using Luzid Local Validator: “Unsupported Program ID” error when calling create_associated_token_account
As a developer using Luzid, a popular blockchain testing platform, you have probably encountered the “Unsupported Program ID” error when executing certain instructions on your local validator. This issue can be frustrating, especially when trying to test and validate token creation and minting processes.
In this article, we will delve into the details of the issue and provide possible solutions to resolve it.
What is Luzid Local Validator?
Luzid is a blockchain testing platform that allows developers to simulate various use cases on their local Ethereum testnet. The platform provides a user-friendly interface for creating wallets, deploying contracts, and executing transactions.
Unsupported Program ID Error
If an instruction has an unsupported Program ID, it means that the transaction or contract call requires a specific Program ID that is not supported by the local Luzid validator. In this case, an error will occur when calling create_associated_token_account because Luzid does not support creating associated tokens with a Program ID other than 0x01.
Why does this happen?
The `Unsupported Program IDerror usually occurs due to outdated or incompatible dependencies in your codebase. When a contract or instruction uses an unsupported Program ID, it will trigger the validation process on the local Luzid validator. However, if the validator does not support this ID, it will return an error message indicating that the Program ID is invalid.
Possible Solutions
To resolve this issue, consider the following steps:
- Update Luzid dependencies
: Make sure you have updated your Luzid dependencies to the latest versions. You can do this by runningnpm install
oryarn installin the terminal.
- Review the contract code: Review the contract code and identify any instructions that use unsupported program IDs. Update these instructions to match supported IDs, if possible.
- Use a different local validator instance: If updating the Luzid dependencies does not resolve the issue, try creating a new local validator instance with a different configuration or IP address. This may help isolate the issue.
- Contact Luzid support: Contact Luzid support for further assistance. They may be able to provide additional instructions or solutions specific to your use case.
Example code snippet
To give you a better idea of how this error might manifest, here is an example code snippet from a simple contract on the Solana blockchain:
import { ProgramId } from '@solana/web3.js';
import { createAssociatedTokenAccount } from './create_associated_token_account';
import { create_luzid_validator } from './create_luzid_validator';
const program_id = ProgramId.fromPubkey('your_program_id');
async function main() {
const validator = wait create_luzid_validator();
// Creating an associated token account
const result = wait create_associated_token_account(validator);
}
In this example, the create_associated_token_accountinstruction uses an unsupported program ID (0x01`). To resolve this issue, you will need to update the instruction to match a supported program ID.
