Not long ago I started receiving this strange error with mail sending in my Laravel application, error is:
ErrorException in EsmtpTransport.php line 55:
Argument 1 passed to Swift_Transport_EsmtpTransport::__construct() must implement interface Swift_Transport_IoBuffer, none given
Interesting thing is that my mailing system worked just fine for about a year, nothing has been updated (just server and domain paid again few weeks back), so I presume that code isn't the problem, I double checked information in mail authentication system, those are right too.
I followed exception stack trace, and found that in Swift_SmtpTransport::__construct() parameters are sent right, but from there Swift_EsmtpTransport::__construct() is called without parameters (which is actually error shown)
Also I updated all my libraries (with "composer update" command). I have no idea what can be wrong, and couldn't find anything that helps online, so any help will be great
Current versions are:
- "laravel/framework": "5.2.*" // from "composer.json"
- "swiftmailer/swiftmailer": "~5.1" (v5.4.6 after update) // from "laravel/framework/composer.json"
--- Edit ---
I found somewhere that this is some kind of loading (Dependency Injection) problem, so I executed this line of code:
var_dump(Swift_DependencyContainer::getInstance()->createDependenciesFor('transport.smtp'));
And got this as result array(0) { }
