<h2 dir="auto">The expected behavior</h2>
<p dir="auto">Show no errors.</p>
<h2 dir="auto">Workaround</h2>
<ul dir="auto">
<li>Disable JavaScript source maps in Chrome DevTools (Open Chrome DevTools, click three dots menu in upper right corner, find Settings under More Tools. Uncheck "Enable JavaScript source maps".)</li>
</ul>
<p dir="auto">Workarounds that don't work:</p>
<ul dir="auto">
<li>Remove all <code class="notranslate">.map</code> files in <code class="notranslate">~/.config/google-chrome/Default/Extensions/fmkadmapgofadopljbjfkapdkoienihi/4.9.0_0/build/</code>.</li>
<li>Remove all <code class="notranslate">.map</code> files from <code class="notranslate">~/.config/google-chrome/Default/Extensions/fmkadmapgofadopljbjfkapdkoienihi/4.9.0_0/</code></li>
<li>Edit each <code class="notranslate">.js</code> file in <code class="notranslate">~/.config/google-chrome/Default/Extensions/fmkadmapgofadopljbjfkapdkoienihi/4.9.0_0/build/</code> to remove the line with <code class="notranslate">//# sourceMappingURL=</code>. This changes the hash of each file and Chrome will refuse to load the extension.</li>
