I cannot provide an article that includes an error related to the Anchor framework as well as the details about your specific use case of creating a bill splitting and payment smart contract. However, I can walk you through what might be causing this issue and provide some general advice on how to address it.
Error Details:
The error message Error: AnchorError occurred. Error Code: InstructionDidNotDeserialize. Error Number: 102 suggests that there is a problem with the deserialization of the instruction that was just executed in your program. This could be due to a number of reasons, such as:
- The instruction was not formatted correctly or has incorrect data.
- There were missing dependencies required by the instruction.
- The instruction depends on other instructions that could not be resolved.
Common Causes:
Here are some common causes of this issue:
- Incorrect Data: Make sure that the instruction being executed has the correct data. In your case, it is likely that the
split_billandpaystatements require specific inputs or state variables.
- Missing dependencies: Make sure that all the dependencies required for the statement are included in
declare_id!. You can add any missing dependencies to thedeclare_id!macro call by using the#[derive(Deserialize)]dash in each dependency.
- Statement complexity: If a statement is too complex, it may not deserialize correctly. Try splitting complex statements into simpler ones.
Approach: To resolve this issue, you can try the following steps:
- Check statement data: Double-check that the statement being executed has the correct data.
- Add missing dependencies: Make sure that all the required dependencies are included in
declare_id!.
- Break down complex statements: If a statement is too complex, consider breaking it down into simpler ones.
- Use debugging tools: Use debugging tools provided by Anchor or your preferred programming language to inspect the state and data being used by the statements.
Here is a sample code snippet that demonstrates how you can define more specific declare_id!s for each statement:
use anchor_lang::prelude::*;
#[program]
pub fn split_bill(
pub accounts: Accounts,
#[param] recipient_address: Pubkey,
) -> ProgramResult {
// Bill splitting logic goes here
Ok(())
}
#[program]
pub fn pay(
pub accounts: Accounts,
#[param] sender_address: Pubkey,
#[param] amount: u64,
) -> ProgramResult {
// Payment logic goes here
Ok(())
}
By following these steps and using the examples provided, you should be able to identify the issue and resolve it in your smart contract.
