Cannot read properties of undefined (reading 'toString') while signing a transaction

Question

I'm getting this error

const key = signer.publicKey.toString();
                                   ^

TypeError: Cannot read properties of undefined (reading 'toString')

I'm trying to use this function

const freeze = await program.methods.freezeToken().accounts({
      sender : sender,
      senderAta : senderAta,
      mint : mint,
      vaultAccount : vaultAccount,
      freezingConfig : freezingConfig,
      tokenProgram : tokenProgram,
      systemProgram : systemProgram,
      rent : rent
    }
  ).signers(walletWrapper.payer).rpc()

For the program account

#[derive(Accounts)]
pub struct FreezeToken<'info> {
    ///CHECK : Not dangerous
   #[account(mut, signer)]
    pub sender: AccountInfo<'info>,
    #[account(mut)]
    pub sender_ata: Account<'info, TokenAccount>,

   pub mint: Account<'info, Mint>,
    #[account(
        init,
        seeds = 
        [   
            b"vault".as_ref(),
            mint.key().as_ref()
        ],
        bump,
        payer = sender,
        token::mint = mint,
        token::authority = sender,
    )]
    pub vault_account: Account<'info, TokenAccount>,   
      ///CHECK : Not dangerous

    #[account(
        init,
        seeds = 
        [   
            b"config".as_ref(),
            mint.key().as_ref()
        ],
        bump,
        payer = sender,
        space = 90
    )]
    pub freezing_config : Account<'info,FreezingConfig>,
    
    /// CHECK: This is not dangerous because we don't read or write from this account
    pub token_program: AccountInfo<'info>,
    pub system_program: Program<'info, System>,
    pub rent: Sysvar<'info, Rent>,
}

I feel i'm missing some parameters or arguments, but i can't figure it out.

The parameters i use are

const sender = new PublicKey("U4NHM8DNT3kCNrRtB9ymgt1mcR6RBaHwUHWLoxM4KTF");
  const senderAta = new PublicKey("2zfkpS8VNWk2t8B2737B6xxFVw8WFNjF3qWXvtQAbgK4");
  const mint = new PublicKey("9jcbX9YT6ZzvEsuUrfxcV8Chv3uz7TMmPo4MXXDc5UhV");
  const vaultAccount = new PublicKey("9UgS3GBfQVmsEMVje5tniYgYszDs5G7orcw8r71Mdesb");

  const freezingConfig = new PublicKey('FK81EDxxU7pPwm5BSs5oFQt5deoRxynuJwu8bnr4nbhf')
  const tokenProgram = new PublicKey("TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA");
  const systemProgram = new PublicKey('11111111111111111111111111111111');
  const rent = new PublicKey("SysvarRent111111111111111111111111111111111");
const walletWrapper =new anchor.Wallet(walletKeyPair);

Answer 1

Your account parameters should be the Public Key of the account, not the Keypair. For instance if you generate a new account using let newAccount = anchor.web3.generate() to pass into your instruction call, pass it in as newAccount: newAccount.PublicKey().
