could not find `__client_accounts_contributor` in the crate root and cannot find type `Withdraw`

Question

My code

use anchor_lang::prelude::*;
use anchor_lang::solana_program::pubkey;

declare_id!("8SQ7LtBoufLSXWbcHf7bXuEzFWksbLjE8T7jUi3Yxz1");

#[program]
pub mod cnft {

    use super::*;

    pub fn withdraw_cnft(ctx: Context<Withdraw>) -> Result<()> {

        let merkle_tree = pubkey!("EwxweDQtWzitdmJabX9irUXHbfjTBKujqWVaFtFGr3Gt");
        let lead_index : u32 = 1u32;

        msg!("Transfering CNFT {} from tree {}" , lead_index, merkle_tree);

        Ok(())
    }
}

#[derive(Accounts)]
pub struct Initialize {}

error

Answer 1

You'll need some the Withdraw type defined to be used as Context<Withdraw>, ie you can just add:

#[derive(Accounts)]
pub struct Withdraw {}
