Using Luzid Local Validator: “Unsupported Program Identifier” error when calling create_associated_token_account
As a developer using Luzid, a popular blockchain testing platform, you have probably encountered the “Unsupported Program Identifier” error when running certain instructions on a local validator. This issue can be frustrating, especially when trying to test and validate token creation and minting processes.
In this article, we will dive into the details of the issue and present possible solutions to fix it.
What is Luzid Local Validator?
Luzid is a blockchain testbed that allows developers to simulate various use cases on their local Ethereum testnet. The platform provides an easy-to-use interface to create wallets, deploy contracts, and execute transactions.
Unsupported Program ID error
When a statement 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, calling create_associated_token_account results in an error because Luzid does not support creating associated tokens with Program IDs other than 0x01.
Why does this happen?
The “Unsupported Program ID” error usually occurs due to outdated or incompatible dependencies in the code base. When a contract or statement uses an unsupported Program ID, a validation process is triggered in the local Luzid validator. However, if the validator does not support this ID, it returns an error message stating 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 running
npm installoryarn installin the terminal.
- Check contract code – Review your contract code to identify any instructions that use an unsupported program ID. Update these instructions to match supported IDs if possible.
- Use a different local validator instance – If updating the Luzid dependency 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 team
– Contact Luzid support team for further assistance. They may be able to provide additional guidance 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:
`salty
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 = await create_luzid_validator();
// Create a linked token account
const result = await create_associated_token_account(validator);
}
`
In this example, thecreate_associated_token_accountstatement uses an unsupported program ID (0x01`). To resolve this issue, update the manual to match the supported program ID.
