<p>I was using the Edge WebDriver, but I changed to Chrome because I thought it'd solve the problem, and unfortunately, it didn't, so I don't think it had anything to do with the Driver, but I'd rather keep with Chrome, if possible.</p>

<p>This is the line that simulates the script:</p>

<pre><code>gc.execute_script("""document.evaluate('//[@id="QRYSELECT_WRK_QRYSEARCHTEXT254"]', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.setAttribute('value','foo')""")
</code></pre>

<p>And it raises me an exception about null pointers, but basically, it's saying that the browser couldn't find this element, and, therefore, couldn't change its value.</p>

<p>Ironically, when I open the console and write the following command (wich is the same script above):</p>

<pre><code>document.evaluate('//[@id="QRYSELECT_WRK_QRYSEARCHTEXT254"]', document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue.setAttribute('value','foo')
</code></pre>

<p>It works.</p>

<p>Here's the traceback to the error when I call execute_script from gc:</p>

<pre><code>Traceback (most recent call last):

</code></pre>

<p>So I guess it's probably something related to permissions...? But I don't know, it's quite weird to get two different results to the same script, isn't it?</p>

<p>Thanks!</p>
