by

Error Explanation:

A TypeError with the message “[err_invalid_arg_type]: the ‘chunk’ argument must be of type string or an instance of buffer or uint8array. received undefined” occurred. This error typically happens when a required argument of type string or buffer is missing or provided as undefined.

Error Examples:

Example 1:

    const chunk = undefined;
    // Assuming some code here that is expecting a chunk argument of type string or buffer
    // Calling the method/function without providing the required argument or providing it as undefined

Example 2:

    const chunk = null;
    // Assuming some code here that is expecting a chunk argument of type string or buffer
    // Calling the method/function with null value instead of a string or buffer

Example 3:

    const chunk;
    // Assuming some code here that is expecting a chunk argument of type string or buffer
    // Declaring the variable without assigning any value, which results in undefined
