Error I am getting:
User warning: block could not be found in _context in "themes/jesse-d8-2013/templates/page.html.twig" at line 34 in Drupal\Core\Template\TwigTemplate->getContextReference() (line 51 of core/lib/Drupal/Core/Template/TwigTemplate.php).

Twig_Error_Runtime: An exception has been thrown during the rendering of a template ("Object of type "Drupal\Core\Field\FieldItemList" cannot be printed.") in "themes/jesse-d8-2013/templates/page.html.twig" at line 34. in Twig_Template->displayWithErrorHandling() (line 279 of /var/sites/jessenicola.dev-vm/core/vendor/twig/twig/lib/Twig/Template.php).Removing line 34 sure enough resolves the issue, but that's where I render the main page content so that doesn't do much good. Changing the main page content (a node) to absolutely nothing doesn't fix it. Changing the name of the region to content, main page content, hell call it something random and it just breaks by placing main page content there.
Page template in question:
<div class="tenOhFiveOuter">
<header>
<h1><a href="{{ front_page }}">

</a></h1>
{% if page.header %}
{{ page.header }}
{% endif %}
<div class="clearBox"><!-- --></div>
</header>
{% if page.contentTop %}
<div class="contentTop">
{{ page.contentTop }}
</div>
{% endif %}
<div id="content">
{{ messages }}
{{ page.help }}
{% if tabs %}
<div class="tabs">{{ tabs }}</div>
{% endif %}
{% if action_links %}
<ul class="action-links">{{ action_links }}</ul>
{% endif %}
{% if page.rightSideBar %}
