I'm currently trying to run an escrow program and when i turn on the solana-test-validator in a different terminal it gives me this error:
failed to send transaction: Transaction simulation failed: Attempt to load a program that does not existWhen I turn that off i get the following error:
failed to get recent blockhash: FetchError: request to http://localhost:8899/ failed, reason: connect ECONNREFUSED 127.0.0.1:8899I'm on the localhost btw
Any help is much appreciated!
EDIT: I have an instruction in my src folder as such:
#[derive(Accounts)]#[instruction(application_idx: u64)]pub struct InitNewExchange<'info> { #[account( init, payer = user_sending, space = Exchange::LEN, seeds = [b"exchange".as_ref(), user_sending.key().as_ref(), user_receiving.key.as_ref(), mint_of_token_being_sent.key().as_ref(), application_idx.to_le_bytes().as_ref()], bump, )] application_exchange: Account<'info, Exchange>, #[account( init, payer = user_sending, seeds = [b"exchange".as_ref(), user_sending.key().as_ref(), user_receiving.key.as_ref(), mint_of_token_being_sent.key().as_ref(), application_idx.to_le_bytes().as_ref()], bump, token::mint = mint_of_token_being_sent, token::authority = application_exchange, )] //Should not be signer or writable escrow_wallet_exchange: Account<'info, TokenAccount>, #[account(mut)] user_sending: Signer<'info>, user_receiving: AccountInfo<'info>, mint_of_token_being_sent: Account<'info, Mint>, #[account( mut, constraint = wallet_to_withdraw_from.owner == user_sending.key(), constraint = wallet_to_withdraw_from.mint == mint_of_token_being_sent.key(), )] wallet_to_withdraw_from: Account<'info, TokenAccount>, system_program: Program<'info, System>, token_program: Program<'info, Token>, rent: Sysvar<'info, Rent>,}and the following handler function for it:
pub fn handler( ctx: Context<InitNewExchange>, application_idx: i64, amount: i64) -> Result<()> { //Assign attributes to Exchange let exchange = &mut ctx.accounts.application_exchange; exchange.idx = application_idx; exchange.user_sending = ctx.accounts.user_sending.key().clone(); exchange.user_receiving = ctx.accounts.user_receiving.key().clone(); exchange.mint_of_token_being_sent = ctx.accounts.mint_of_token_being_sent.key().clone(); exchange.escrow_wallet = ctx.accounts.escrow_wallet_exchange.key().clone(); exchange.amount_tokens = amount; exchange.bump = *ctx.bumps.get("application_exchange").unwrap(); msg!("Initializing exchange instance for {} tokens", amount); let bump_vector = exchange.bump.to_le_bytes(); let mint_of_token_being_sent_pk = ctx.accounts.mint_of_token_being_sent.key().clone(); let application_idx_bytes = application_idx.to_le_bytes(); let sender = ctx.accounts.user_sending.key(); let receiver = ctx.accounts.user_receiving.key(); let inner = vec![ b"exchange".as_ref(), sender.as_ref(), receiver.as_ref(), mint_of_token_being_sent_pk.as_ref(), application_idx_bytes.as_ref(), bump_vector.as_ref(), ]; let outer = vec![inner.as_slice()]; let transfer_instruction = Transfer{ from: ctx.accounts.wallet_to_withdraw_from.to_account_info(), to: ctx.accounts.escrow_wallet_exchange.to_account_info(), //Authority will be the one sending authority: ctx.accounts.user_sending.to_account_info(), }; let cpi_ctx = CpiContext::new_with_signer( ctx.accounts.token_program.to_account_info(), transfer_instruction, outer.as_slice(), ); anchor_spl::token::transfer(cpi_ctx, exchange.amount_tokens.try_into().unwrap())?; Ok(())}and I ran anchor build, anchor deploy (both working), and anchor test (which did not work). The erroneous code comes from this chunk in my test file (but i think all my programs.method calls incur this error):
const tx1 = await program.methods .initNewExchange(pda.idx, amount) .accounts({ applicationExchange: pda.exchangeKey, escrowWalletExchange: pda.escrowWalletKey, userSending: sender.publicKey, userReceiving: receiver.publicKey, //Account data type of mint mintOfTokenBeingSent: mintAddress, //Wallet of sender for that particular token walletToWithdrawFrom: senderWallet, systemProgram: anchor.web3.SystemProgram.programId, tokenProgram: spl.TOKEN_PROGRAM_ID, rent: anchor.web3.SYSVAR_RENT_PUBKEY, }) .signers([sender]) .rpc();THANKS A LOT once again!!
