How can I fix this error?

RuntimeException
Please batch json rpc first.

Web3\Providers\HttpProvider::execute
vendor/sc0vu/web3.php/src/Providers/HttpProvider.php:91

 */

public function execute($callback)

{

    if (!$this->isBatch) {

        throw new \RuntimeException('Please batch json rpc first.');

    }

    $methods = $this->methods;

    $proxy = function ($err, $res) use ($methods, $callback) {

        if ($err !== null) {

            return call_user_func($callback, $err, null);

        }
