I’m happy to help you troubleshoot Solana runtime errors. However, please note that since this is a GitHub repository, I’m providing some guidance on how to approach the issue.
Error Message Analysis
The ERROR String contains invalid character error message indicates that there is a problem with a string literal in your codebase. Specifically, it appears that you are trying to create a base64 encoded array using Solana’s base64ToUint8Array() function.
In this case, the problem is that the base64ToUint8Array() function expects a valid base64 encoded byte string as input. However, the code is trying to pass it an invalid string.
Possible Cause
The possible cause of this error could be one or more of the following:
- Invalid Base64 Encoding: Make sure that you are encoding and decoding strings correctly using base64. You can use online base64 validators to verify that the data you enter is valid.
- Malformed string input: Verify that the input string is properly formatted, does not contain leading or trailing spaces, and does not contain any special characters that are allowed in a base64 encoded byte array (e.g.
+/--=).
- Invalid character encoding: The character set used for encoding and decoding in the Solana runtime must match the character set used for input/output operations. Make sure that your code sets the character encoding correctly.
Troubleshooting steps
To resolve this issue, try the following:
- Check Base64 encoding: Use online Base64 validators to verify that the input string is encoded correctly.
- Validate input string: Make sure that the input string does not contain leading or trailing spaces and can only contain allowed characters (e.g. letters, numbers, special characters).
- Check character encoding: Make sure that the character encoding used for input/output operations matches the Solana runtime.
- Test with sample string: Try creating a sample base64 encoded byte array using “base64ToUint8Array()” and pass it to the code to check if the issue still occurs.
GitHub repository
Here is an example of how you can modify your frontend and backend code to fix the error:
// In frontend.js
const base64 = request('base64-js');
function createBase64ByteString(input) {
const encoded = base64.stringify(input);
return encoded;
}
// In backend.js
async function main() {
try {
// Create a sample input string with a valid charset (e.g. "hello")
const inputString = 'hello';
// Use the createBase64ByteString function to encode the input string as a base64 encoded byte array
const base64EncodedArray = createBase64ByteString(inputString);
console.log(base64EncodedArray);
} catch (error) {
console.error(error);
}
}
If you follow these troubleshooting steps and use online verification tools, you can resolve the issue with Solana runtime errors. If the issue persists after trying the fixes, please provide more details about your codebase and error messages for further assistance.
Note: Since this is a GitHub repository, be sure to make the changes you made to resolve the issue and push the updated codebase to your repository.
