<p dir="auto">Hi all,</p>
<p dir="auto">first and foremost, thanks very much for Next.js. It's great.</p>

<ul class="contains-task-list">
<li class="task-list-item"><input type="checkbox" id="" disabled="" class="task-list-item-checkbox" checked=""> I have searched the <a href="https://github.com/zeit/next.js/issues">issues</a> of this repository and believe that this is not a duplicate.</li>
</ul>
<h2 dir="auto">Expected Behavior</h2>
<p dir="auto">In versions prior to 5, our ssr was functioning as expected for every page.</p>


<h2 dir="auto">Current Behavior</h2>
<p dir="auto">Since we upgraded to 5, the page mapped as in<br>
<a href="https://github.com/em-casa/frontend/blob/master/server.js#L39">https://github.com/em-casa/frontend/blob/master/server.js#L39</a><br>
started flashing 404 and displaying if rendered server-side (losing the context).</p>
<p dir="auto">I ended up making a bare-bones page just to make sure, see<br>
<a href="https://github.com/em-casa/frontend/blob/fix-filtered-calls-to-url/pages/listings/index.js">https://github.com/em-casa/frontend/blob/fix-filtered-calls-to-url/pages/listings/index.js</a><br>
and it still happens.</p>


<h2 dir="auto">Steps to Reproduce (for bugs)</h2>


<ol dir="auto">
<li>In production: <a href="https://emcasa.com/imoveis" rel="nofollow">https://emcasa.com/imoveis</a></li>
<li>A branch that if cloned will reproduce the issue without needing the backend:<br>
<a href="https://github.com/em-casa/frontend/tree/fix-filtered-calls-to-url">https://github.com/em-casa/frontend/tree/fix-filtered-calls-to-url</a></li>
<li>If testing locally, the page in question is <code class="notranslate">localhost:3000/imoveis</code></li>
</ol>
<h2 dir="auto">Context</h2>
<p dir="auto">I tried to make sure this isn't an Express issue or anything of the sort. Wonder if anyone has been experiencing something similar. Any help will be greatly appreciated.</p>
