Missing elements come back as None, not exceptions - check before clicking

TL;DR

Check for None right after the query and handle the not-found case explicitly, especially on pages where the element is conditional.

Steps

1. Always None-check query response fields before interacting. A missing element comes back as None on the response object, not an exception - so response.search_box.click() on a page without that element throws an AttributeError on None, far from the real cause. Check for None right after the query and handle the not-found case explicitly, especially on pages where the element is conditional.

When to use

You are seeing this: Always None-check query response fields before interacting. Use this skill when you run into "Missing elements come back as None, not exceptions - check before clicking".

When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

Source: AgentQL official docs (First steps): the response object mirrors your query structure, and a field is None when the described element was not found on the page - it does not raise.

Verified resolution: Always None-check query response fields before interacting. A missing element comes back as None on the response object, not an exception - so response.search_box.click() on a page without that element throws an AttributeError on None, far from the real cause.
