can you enable YII_DEBUG in the apidoc command: https://github.com/yiisoft/yii2-apidoc/blob/master/apidoc#L11 ? and paste the stack trace?

[itnelo]

got it.

In one of my classes i have invalid annotation:

@var Route[]|[]

It completely broke apidoc.

$types become

0 => [
    0 => '\\app\\modules\\routing\\models\\Route[]'
    1 => '[]'
]

and in case of '[]' exception was thrown

[cebe]

fixed, thanks for digging into it!
