Can't use with this SDK

[KingYes]

Hi.. I get this error:

 Catchable fatal error: Argument 1 passed to React\Promise\Promise::__construct() must be callable, null given, called in /home/yakir/slack-app/vendor/react/promise/src/Deferred.php on line 25 and defined in /home/yakir/slack-app/vendor/react/promise/src/Promise.php on line 16

That's the code:

use \Maknz\Slack\Client;

include( __DIR__ . '/vendor/autoload.php' );
$settings = [];
$client = new Client( 'my.endpoint', $settings );
$client->send( 'Test msg' );

Looks like something to do with React, no? If you can trace it back to a code problem in this library I'll take a look.

Nope. I don't change anything.. just download from compress. How I can trace it back for you?

[maknz]

The stack trace you provided only mentions React, I haven't really got any reason to think there's a problem with this package.

How I can give you this log?

[maknz]

Probably around where you got your original stack trace? Further down? Above? Does it mention an error in this package somewhere?

Nope. Just if I use send() method I get this error

[KingYes]

Maybe that error cuz I run your code from WordPress?

[KingYes]

I get log from the error, please give me your email to send you this file..

[maknz]

Thanks for that. Looks like a problem with Guzzle or the data we're passing to Guzzle. I'll look into it and maybe get hold of the Guzzle people to see if they have any ideas. It looks like you're doing everything correctly, though.

[KingYes]

Okay, Thanks.

[maknz]

Can you try specifying an older version of Guzzle to see if 5.3.0 is the problem? Try specifying "guzzlehttp/guzzle": "5.0.0" in your project's composer.json file. If that fails, try using 4.0.0.

If that works, we can fairly certainly say Guzzle is the problem, otherwise there could be an issue in how we're calling it.

[maknz]

Also, I notice you made that Gist secret, but do you mind if I provide it to the Guzzle maintainers?

[KingYes]

Okay, I try with 5.0.0 version and same error. But with 4.0.0 it's seem work's perfect. And you can send this to Guzzle maintainers.

[maknz]

Excellent. Change your 4.0.0 constraint to ~4.0 so you get at least the latest version of 4.x.

I've opened an issue with Guzzle, hopefully they can shed some light. I'm fairly certain there must be a problem with your environment as nobody else has had any issue with Guzzle 5, but they might have seen it before.

[maknz]

Closing this because the problem is isolated to your environment and isn't affecting other users, and the issue relates to Guzzle rather than this package.
