Fix Solana Devnet Error
As a developer working on the Solana blockchain, you may have encountered the “Invalid Boolean” error while interacting with Solana Devnet. This article will help you troubleshoot and resolve this issue.
What is the “Invalid Boolean” error?
The “Invalid Boolean” 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 most often occurs when you are trying to send or receive transactions on Solana Devnet.
Causes of the “Invalid Boolean” error
The main cause of this error lies in the “WrappedLayout” module, which handles the logical decoding of various functions and APIs. The specific issue often stems from poor handling of Boolean values, such as:
- Mixing Boolean values with other numeric types (e.g. using a number that should be a Boolean)
- Passing non-Boolean values through a function that expects a Boolean value
- No conversion or proper conversion between different data types
How to fix the error
To resolve this issue, follow these steps:
- Check your code: Check your codebase for functions or APIs that could cause the WrappedLayout module to receive non-Boolean inputs.
- Use a Boolean 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 Boolean values properly.
- Use correct cast
: When passing non-Boolean values through a function that expects a Boolean, make sure you use the correct cast method (e.g., “toBool” or “toBool”).
- Validate input: Always validate and clean up user-supplied input to ensure it conforms to expected formats.
- Check for errors in operations: Verify that all operations sent over Devnet are properly formatted and contain all required fields.
Example: Using the Boolean Wrapper Library
Here is an example of how you can wrap Boolean values using “solana-typed-arrays”:
import { typedArray } from 'solana-type-arrays';
const wrappedBool = (x) => {
return typedArray(x, [bool]);
};
// Use:
const boolValue = wrappedBool(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 boolean inputs.
Conclusion
The Solana Devnet “Invalid Boolean Value” error can be resolved by carefully reviewing your code, using the correct conversion and wrapping libraries, validating your input, and checking for errors in your operations. After following these steps, you should be able to resolve this common issue and continue working with Devnet with confidence.
