Connection pool - Promise returned from advance() must resolve

[NicklasWallgren]

How to reproduce the issue at hand.

$pool = Amp\Mysql\pool('<connection string>');
$promise = $pool->query('SELECT 1');
$resolved = \Amp\Promise\wait($promise);

var_dump($resolved->getCurrent());

$pool->close();

Uncaught Error: Promise returned from advance() must resolve before calling this method in /Users/.../vendor/amphp/amp/lib/Internal/Producer.php on line 75

You need to call advance and await the returned promise before calling getCurrent.

[NicklasWallgren]

Could you provide an example of this in a synchronous environment?

The example provided above works fine in earlier versions of amphp/mysql.

[Bob Weinand]

yeah, you're missing a \Amp\Promise\wait($resolved->advance()); before the call to getCurrent().
