<p dir="auto">Issues like <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="200861457" data-permission-text="Title is private" data-url="https://github.com/vercel/next.js/issues/774" data-hovercard-type="issue" data-hovercard-url="/vercel/next.js/issues/774/hovercard" href="https://github.com/vercel/next.js/issues/774">#774</a> &amp; <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="205090071" data-permission-text="Title is private" data-url="https://github.com/vercel/next.js/issues/972" data-hovercard-type="issue" data-hovercard-url="/vercel/next.js/issues/972/hovercard" href="https://github.com/vercel/next.js/issues/972">#972</a> are fine <strong>as long as the new entry-point can have vendors &amp; <code class="notranslate">commons.js</code> extracted the same as <code class="notranslate">main.js</code></strong>.</p>
<p dir="auto">Resolving this <em>requires exporting a different webpack config</em>, but the signature <strong>requires</strong> <code class="notranslate">return config;</code>, as <code class="notranslate">return [config, otherEntryConfig];</code> fails.</p>
<p dir="auto">If an array of configs were supported by default, having separate build targets (e.g. <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="209446314" data-permission-text="Title is private" data-url="https://github.com/vercel/next.js/issues/1245" data-hovercard-type="issue" data-hovercard-url="/vercel/next.js/issues/1245/hovercard" href="https://github.com/vercel/next.js/issues/1245">#1245</a>) &amp; entry-points could be possible.</p>
<p dir="auto">Sometime that error show in log, I don't know when or how that error show up, it just show up random<br>
It seem like I do something wrong but I don't know what</p>
