This error occurs when the first argument passed to a function must be one of the mentioned data types, but it is not.
To resolve this error, you should check the argument being passed to the function and make sure it is of the correct data type. For example, if the function expects a string as the first argument, you can use the `typeof` operator to check if the argument is a string before passing it to the function:
```
function myFunction(str) {
if (typeof str !== 'string') {
throw new TypeError('First argument must be a string');
}
// rest of the function code here
}
```
This will throw an error if the first argument is not a string, allowing you to catch the error and fix it.
