<p dir="auto">Right now, we get the following errors during our build. I think this is because we have almost empty files inside of <code class="notranslate">web/e2e_test</code> that look like this:</p>
<p dir="auto">E.g. compiler_perf.dart</p>
<div class="snippet-clipboard-content notranslate position-relative overflow-auto" data-snippet-clipboard-copy-content="library benchmarks.e2e_test.compiler_perf;
main() {}"><pre class="notranslate"><code class="notranslate">library benchmarks.e2e_test.compiler_perf;
main() {}
</code></pre></div>
<p dir="auto">The error in the build is as follows:</p>
