public function getVariableName() : ?string
{
return $this->variableName;
}

@elvispdosreis What version of zendframework/zend-code are you using (composer show)? As I can see VarTag support has been added in 3.2.0 - PR #41 and it requires PHP 7.1.

[elvispdosreis]

"zendframework/zend-soap": "^2.6",

@elvispdosreis sorry, I've asked for zend-code, not zend-soap. as you said, the issue seems to be in file:

 \vendor\zendframework\zend-code\src\Reflection\DocBlock\Tag\VarTag.php69
                       ^^^^^^^^^^

it seems that the zend-code version is incompatible with php7.0

@elvispdosreis as I said, since zend-code 3.2.0 supports only PHP7.1. I have no idea how then you've install it. Please check your dependencies (you can share composer show results here) and run update (composer update) to update your dependencies. Have you install with --ignore-platform-reqs? I can't see any issue with libraries, this is just problem with your installation.
