<p>When upgrading a TYPO3 from v10 to v11 I got the following deprecation notice:</p>
<blockquote>
TYPO3 Deprecation Notice:
Class TYPO3CMSExtbaseObjectObjectManager is deprecated and will be removed in TYPO3 12.0
in /var/www/typo3/public/typo3/sysext/extbase/Classes/Object/ObjectManager.php line 104</blockquote>
<p>The error stemmed from sysext/fluid - it could not load ViewHelpers via the symfony dependency container.</p>
<p>The solution was to define the namespace prefix in our extension's <tt class="docutils literal">Configuration/Services.yaml</tt>:</p>
<pre class="literal-block">
Vendor\Extname\:
resource: '../Classes/*'
</pre>
