Solana: Error: Invalid boolean: 142

Solana Devnet Error Resolution

As a developer working with the Solana blockchain, you may have come across the “Invalid bool” error while interacting with Solana Devnet. This article will provide you with tips on how to resolve this issue.

What does the “Invalid bool argument” error mean?

The “Invalid bool type” error occurs when the “WrappedLayout” module in your code tries to decode a boolean value that is not one of the defined types (e.g. “0”, “1”, etc.). This error usually occurs when you try to send or receive transactions on the Solana Devnet network.

Causes of the “Invalid bool” error

The main cause of this error is the WrappedLayout module, which handles decoding booleans for various functions and APIs. This particular issue is often caused by incorrect handling of booleans, such as:

• Mixing booleans with other numeric types (e.g. using a number where a boolean should be)

• Passing non-boolean values ​​through a function that expects a boolean

• Incorrect casting or conversion between different data types

How ​​to fix the bug

To fix this issue, follow these steps:

• Review your code

  : Review your codebase for any functions or APIs that might cause the WrappedLayout module to receive non-boolean input.

• Use a boolean wrapper library

  

  : Consider using libraries such as solana-type-arrays or solana-types, which provide predefined types and wrappers for Solana data structures, including booleans. These libraries can help ensure that your code handles booleans correctly.

• Use proper casts: When passing non-boolean values ​​through a function expecting a boolean value, make sure you use the correct cast method (e.g. toBool or toBoolean).

• Validate input: Always validate and sanitize user-supplied input to ensure it conforms to expected formats.

• Check for errors in transactions: Verify that all transactions sent in Devnet are properly formatted and contain all required fields.

Example: Using a boolean wrapper library

Here is an example of how you can wrap booleans using solana-type-arrays:

import { typedArray } from 'solana-type-arrays';
const wrappedBool = (x) => {
return typedArray(x, [bool]);
};
// Usage:
const boolValue = coveredBool(1); // Returns an array with a single boolean value

In this example, the wrappedBool function takes a boolean value as input and returns an array containing only that boolean value. This ensures that the WrappedLayout module receives valid bool input.

Conclusion

The « Invalid bool parameter » error in Solana Devnet can be resolved by carefully reviewing the code, using the correct cast and wrapper libraries, validating the input, and checking the transactions for errors. By following these tips, you should be able to overcome this common problem and continue working in Devnet without worries.
