Additional context

count(): Argument #1 ($value) must be of type Countable|array, int given {"exception":"[object] (TypeError(code: 0): count(): Argument #1 ($value) must be of type Countable|array, int given at /home/ss/application/vendor/predis/predis/src/Command/Redis/HGETALL.php:37) [stacktrace] #0 /home/ss/application/vendor/predis/predis/src/Command/Redis/HGETALL.php(37): count(0) #1 /home/ss/application/vendor/predis/predis/src/Client.php(359): Predis\Command\Redis\HGETALL->parseResponse(0) #2 /home/ss/application/vendor/predis/predis/src/Client.php(303): Predis\Client->executeCommand(Object(Predis\Command\Redis\HGETALL))

It look like in this function is called at random times for some random reason with $data is coming in as an int which is blowing up as count() is not expecting an int.

public function parseResponse($data) { $result = [];

    for ($i = 0; $i < count($data); ++$i) {
        $result[$data[$i]] = $data[++$i];
    }

    return $result;
}

I think changing it this would be a safe code change and solve this issue (since the code say that $data is array|null|string):

public function parseResponse($data) { $result = [];

    if (is_countable($data)) {
       for ($i = 0; $i < count($data); ++$i) {
          $result[$data[$i]] = $data[++$i];
       }
    }

    return $result;
}

Thanks!
