This is because while <code>puppeteer</code> uses <code>Function.prototype.toString()</code> to serialize functions while transpilers could be changing the output code in such a way it&#x27;s incompatible with <code>puppeteer</code>.</p><p>Some workarounds to this problem would be to instruct the transpiler not to mess up with the code, for example, configure TypeScript to use latest ecma version (<code>&quot;target&quot;: &quot;es2018&quot;</code>).
