I cloned this repo: solana-movie-program and deployed it on Solana Playground.

I also cloned solana-movie-client and tried it but I get the error: "Transaction simulation failed: Error processing Instruction 0: insufficient account keys for instruction"

Also here are the logs:

[

  ]
}

Does anyone know how to fix it? Thanks!

Try using code from the starter branch: https://github.com/Unboxed-Software/solana-movie-program/tree/starter

That client code builds the instruction like this: https://github.com/Unboxed-Software/solana-movie-client/blob/main/src/index.ts#L61

const instruction = new web3.TransactionInstruction({
        programId: programId,
        data: buffer,
        keys: [
            {
                pubkey: signer.publicKey,
                isSigner: true,
                isWritable: false
            },
            {
                pubkey: pda,
                isSigner: false,
                isWritable: true
            },
            {
                pubkey: web3.SystemProgram.programId,
                isSigner: false,
                isWritable: false
            }
        ]
    })

Which matches these three accounts in the starter branch: https://github.com/Unboxed-Software/solana-movie-program/blob/starter/src/processor.rs#L53

let  initializer = next_account_info(account_info_iter)?; 
let  pda_account = next_account_info(account_info_iter)?; 
let  system_program = next_account_info(account_info_iter)?;

However, if you used the main branch, there's four accounts, which might be the cause for the error you're seeing: https://github.com/Unboxed-Software/solana-movie-program/blob/main/src/processor.rs#L55

let initializer = next_account_info(account_info_iter)?;
let pda_account = next_account_info(account_info_iter)?;
let pda_counter = next_account_info(account_info_iter)?;
let system_program = next_account_info(account_info_iter)?;

Here is the written content for this example program (the branches are for different sections): https://soldev.app/course

  • That is the correct answer. However I get the error: "RangeError: Trying to access beyond buffer length" Jan 6, 2023 at 2:06
