This error usually occurs when you are trying to use the Buffer
class in Node.js to create a buffer from a string or an array of bytes, and the string or array of bytes is not in the correct format.
To fix this error, you can try the following:
- Make sure that you are passing in a string of 12 bytes or a string of 24 hex characters to the
Buffer
constructor. You can use theBuffer.byteLength
method to check the length of the string. - If you are passing in an array of bytes, make sure that it contains only valid byte values (i.e., integers between 0 and 255).
- If you are passing in a string of hex characters, make sure that it contains only valid hex characters (i.e., the characters ‘0’ through ‘9’ and ‘a’ through ‘f’).
- If you are trying to create a buffer from a string that is not in the correct format, you can try using the
Buffer.from
method instead of theBuffer
constructor. TheBuffer.from
method can take a string and an encoding parameter, and it will create a buffer from the encoded version of the string.
For example:
const buffer = Buffer.from('hello world', 'utf8');
This will create a buffer containing the UTF-8 encoded version of the string ‘hello world’.
