Error processing Instruction 0: custom program error: 0xa1 Decimal 161

[AuroraLantean]

Hi Henry, Okay Anchor package has just been updated to 0.12.0, so I have updated the Rust program dependencies to Anchor 0.12.0 in the Cargo.toml file: [dependencies] anchor-lang = "0.12.0" anchor-spl = "0.12.0"

And updated Anchor.toml... And also updated project-serum/anchor to 0.12.0

Then updated the Rust program as below according to the latest IpoPool example in the Anchor examples: const provider = anchor.Provider.local(); anchor.setProvider(provider);

Replace "program.provider" by "provider"

const usdcMint = await createMint(provider); const dataAccount = anchor.web3.Keypair.generate();

await program.rpc.initializeUser(.. {}, //signers: [dataAccount], //instructions: [await program.account.dataAccount.//createInstruction(dataAccount)], )

Please see my forked repo: https://github.com/AuroraLantean/SolanaAnchorDemo1 $ yarn install $ yarn run t1 ... this should give you a successful test result for your MeMe-Num tutorial.

$ yarn run t2 ... this will give you an error below for your Dog Money tutorial.

0xa1 in hex is 161 in decimal From your instruction of finding the error code: https://www.notion.so/Debugging-Custom-Anchor-Errors-b8540dd418c44a4e939ab17c56a3fd3b https://github.com/project-serum/anchor/blob/master/lang/src/error.rs but I could not find the error code for 161... please help! Thank you

Here is error code 161 https://github.com/project-serum/anchor/blob/f6329ceef1f06bfdb2168005234cdf408124727d/lang/src/error.rs#L53

It's possible you're passing in an uninitialized program account. This would result in getting an error saying your 8 bytes discriminator is missing

Henry, I was using your code with slight modification... and I did not change the pub struct InitializeUser<'info> {...} How come the code does not work? According to https://project-serum.github.io/anchor/tutorials/tutorial-1.html#initialize-instruction, it seems I need to add this #[account(init)] on one of the InitializeUser struct's fields, and I tried it with no success... Now I have even reduced the program code to:

#[program]
pub mod dog_money {
    use super::*;
    pub fn initialize_user(ctx: Context<InitializeUser>) -> ProgramResult {
        Ok(())
    }
}
#[derive(Accounts)]
pub struct InitializeUser<'info> {
    //#[account(init)]
    program_signer: AccountInfo<'info>,
    #[account(associated = authority, with = usdc_mint)]
    user_data: ProgramAccount<'info, UserData>,
    #[account(signer)]
    authority: AccountInfo<'info>,
    usdc_mint: CpiAccount<'info, Mint>,
    rent: Sysvar<'info, Rent>,
    system_program: AccountInfo<'info>,
}
#[associated]//#[account]
pub struct UserData {
    pub first_deposit: i64,
}

And with your Anchor testing code:

    await program.rpc.initializeUser({
      accounts: {
        programSigner,
        userData,
        authority: provider.wallet.publicKey,
        usdcMint,
        rent: anchor.web3.SYSVAR_RENT_PUBKEY,
        systemProgram: anchor.web3.SystemProgram.programId,
        clock: anchor.web3.SYSVAR_CLOCK_PUBKEY,
      },
      // signers: [dataAccount],
      // instructions: [await program.account.userData.createInstruction(dataAccount)],
    });

Any idea where the bug is? Thank you

[Henry-E]

    #[account(associated = authority, with = usdc_mint)]
    user_data: ProgramAccount<'info, UserData>,

you're missing init here

[Henry-E]

the associated syntax is going away though and being replaced with seeds so you might want to play around with that syntax instead.

[AuroraLantean]

Okay actually I have tried it:

[account(associated = authority, with = usdc_mint, init)]

...

[associated]

pub struct UserData { pub first_deposit: i64, }

Then I got this: error[E0599]: no function or associated item named default found for struct UserData in the current scope --> programs/dog-money/src/lib.rs:14:10	14	#[derive(Accounts)]	^^^^^^^^ function or associated item not found in UserData ... 41	pub struct UserData {	------------------- function or associated item default not found for this

[Henry-E]

Add the default attribute

Hi Henry, I got it!

#[associated]
pub struct UserData {
    pub first_deposit: i64,
}
impl Default for UserData {
  fn default() -> UserData { 
    UserData{
      __nonce: 0,
      first_deposit: 0,
    }
  }
}

Regarding the seeds syntax, I tried those but none of them worked:

[account(seeds = [authority])]

[account(seeds)]

[account(seeds = [authority, usdc_mint])]

may I know how to do it? As a token of thanks for the videos you made, you can use my code with all Anchor's latest modification! https://github.com/AuroraLantean/SolanaAnchorDemo1 Thank you!

[Henry-E]

Check the anchor repo for example usage of the seeds syntax
