Solana: 8 byte discriminator did not match what was expected when initail PDA account
I can help you write an article about the problem you experience in the Solana PDA account (program data program account).
Title:
Error in 8 bytes discriminator on the initial PDA account on the solana node
Introduction:
Solana is a rapid and scalable decentralized blockchain platform that uses a consensual algorithm called Seven (POS). One of Solana’s most important features is the ability to create data data (PDA), which is used to store data on the network installed on the network. In this article, we will discuss a mistake that can occur in the Solana node by booting the PDA account.
The question:
In the Init function, the 8 to by-by-by-by-boy-by-by-law-by-by-bye chain function per dog does not correspond to the expected value when creating a new PDA account . This difference can cause errors during the boot process.
Code Explanation:
For a better understanding of the problem, let’s look at the details of the code that creates a new PDA account:
`Solana
Import {program_data_account_type} of “@solana/web3.js”;
Import {CREATEPROGRAMATAACCOUNT} of “.
CONST MAIN PROGRAMID = “MAIN PROGRAM-ID”; // Replace your main program ID
ConstialPDAPBUBE = WAIT PROGRAMIDTOPUBKEY (Main Programid);
Constart initialdeserielispkey = Waiting the ProgramTopubkey (“Desarialize”);
Constt Residual Pubkey = Wait programtopubey (“remaining”);
CONST PDAACCOUNTINITPAREMS = {{
Pudges: [
{{
Type: Program_Data_account_Type,
VALUE: INITIALPDAPUBE,
},
{Type: program_data_account_type, value: residual public},
],
};
Const PDAACCOUNT = WAIT CREATIVEACCOUNT (PDAACCOUNITINITPARAS);
`
The error:
After reviewing the details of the code, we can see that the object “PdaaccountinitParams” has two “public”. However, the expected value only applies to one of them (`pdapubkey ''). Because of this difference, the 8 byte discriminator does not consult expectations.
Conclusion:
To solve the problem, you need to update the code details to match both "Pudges" on the 'PDAACCOUNTINITRAMS' object. Here is the updated version of the code:
Solana
Import {program_data_account_type} of “@solana/web3.js”;
Import {CREATEPROGRAMATAACCOUNT} of “.
CONST MAIN PROGRAMID = “MAIN PROGRAM-ID”; // Replace your main program ID
ConstialPDAPBUBE = WAIT PROGRAMIDTOPUBKEY (Main Programid);
Constt Residual Pubkey = Wait programtopubey (“remaining”);
CONST PDAACCOUNTINITPAREMS = {{
Pudges: [
{Type: program_data_account_type, value: Inaialpdapubkey},
{Type: program_data_account_type, value: residual public},
],
};
Const PDAACCOUNT = WAIT CREATIVEACCOUNT (PDAACCOUNITINITPARAS);
`
By updating the “PDAACCOUNTINITPAAMS” object, you should be able to resolve the error and successfully initialize the PDA account in the Solana node to insert the Pudges.
