Solana: The smart contract runs fine on the Solana Playground, but gives error on my local machine.(not found in this scope)

Sorana: Intelligent Agreement works well at the Sorano playground but gives an error on a local machine

As a smart contract programmer, especially for popular platforms, such as Ethereum and Sorana, it is necessary to ensure that your code is assembled and works properly in different environments. In this article, we explored what went wrong with a simple voting agreement written in Rust, which went smoothly at the Soran playground but did not start on my local machine.

Command

Our intelligent agreement is designed to create an interactive research app in which users can prefer to vote for the script. The agreement uses Solana SDK (Packaging S It is written in rust and most functions are performed using a subscription to the «Soran-Program» app.

Here’s a brief overview of the agreement:

`rust

Use Solan_ Process :: {{

Account_info :: Next_account_info,

EntryPoint :: {Get_event_address, call},

Msg,

Program_error :: {program

PubKey :: Pubkey,

};

Use Solan_sdk :: {{

Error :: Error as Solanerror,

Keypair :: keyboard,

Transaction :: {Sami, dedication, preparationsactionerror},

};

// Function to create a new research

Pub Fn Create_pon (

PubKey: & PubKey,

Result: string,

) -> Programsult {{

// Create a new survey manifestation

Allow me to bother = pool :: new ();

Pool.set_outcom (result);

// Get the following account information information

Enter user_account_info = pool.get_next_account_info (). Wait?;

Let Account_keypair = User_account_info.KEY;

// Call the Create_poll function to the user account

reconcile (

& Account_keypair,

Create_poll_callback,

& Pool,

& [[

Account_keypair,

Next_account_info (),

],].

Dedication :: Finally,

IN

Iche

// Function to update the survey results

Pub fn update_poll (end result: string) -> program-

// Update the questionnaire with a new result

Allow me to bother = pool :: new ();

Pool.set_outcom (result);

// Get the following account information information

Enter user_account_info = pool.get_next_account_info (). Wait?;

Let Account_keypair = User_account_info.KEY;

// call the Update_poll function in the user account

reconcile (

& Account_keypair,

Update_poll_callback,

& Pool,

& [[

Account_keypair,

Next_account_info (),

],].

Dedication :: Finally,

IN

Iche

// Inquiring Creation and Update Function of Refund

Pub Fn Create_poll_callback (

Account_info: & Accountinfo,

Pool: and pool,

) -> Programsult {{

// Create a new survey manifestation

Allow me to bother = pool :: new ();

Swimming pool

Ok (obligation :: Finally)

Pub fn update_poll_callback (

Pool: and pool,

Allow me to bother = pool :: new ();

Pool.Set_outcom (Account_info.data.Borrow (). As_str ())?;

While checking the code more details, we can see thatCreate_poll_callbackI Update_poll_Callback` will restore the» Program Program «defined by Sorana SDK. However, there is no explicit definition of type.

Solution

To correct the topic, I have made two changes in the contract:

1.
