The method setRuleError() does not exist on Enjoys\Forms\Element. It seems like you code against a sub-type of said class. However, the method does not exist in Enjoys\Forms\Elements\Optgroup or Enjoys\Forms\Elements\Submit or Enjoys\Forms\Elements\Option or Enjoys\Forms\Elements\Button or Enjoys\Forms\Elements\Image or Enjoys\Forms\Elements\Reset or Enjoys\Forms\Elements\Header. Are you sure you never get one of those?

150 of type integer is incompatible with the type Enjoys\Traits\type expected by parameter $defaults of Enjoys\Forms\Captcha\CaptchaBase::getOption().

'qwertyuiopasdfghjklzxcvbnm1234567890' of type string is incompatible with the type Enjoys\Traits\type expected by parameter $defaults of Enjoys\Forms\Captcha\CaptchaBase::getOption().
