userData: Uncaught Error: Function name must be a string

[Marc008]

Hello,

I plan to add the userData function, but following the example from the doc, I got this error:

PHP Fatal error: Uncaught Error: Function name must be a string in /project/vendor/jaggedsoft/php-binance-api/php-binance-api.php:2094
Stack trace:

My code is:

$Binance = new Binance\API($key, $secret);

try {
    $Binance->userData($balance_update, $order_update);
} catch (Exception $e) {
    print_r($e->getMessage());
}

$balance_update = function($api, $balances) {
    print_r($balances);
    echo "Balance update".PHP_EOL;
};

$order_update = function($api, $report) {
    echo "Order update".PHP_EOL;
    print_r($report);
};

Platform:

• Linux 4.9.0-8-amd64 Wrong issue... #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux

php version:

• PHP 7.0.33-0+deb9u1 (cli) (built: Dec 7 2018 11:36:49) ( NTS )

Any idea what could I be doing wrong?

Thanks in advance.

I updated the version to:

composer require "jaggedsoft/php-binance-api @dev"
and it's fixed.
