Reading the Traceback Like a Senior

Find your line first

Start at the bottom: the exception and its message. Scan up to the first frame in your repo — that is where your assumption broke. Everything else is the library doing its job.

The big three, and what each one means

• StaleElementReferenceException — you found the element, then the page re-rendered, and your handle points at a dead node. Re-find it after the render; don't cling to the old reference.
• ElementClickInterceptedException — the element is there, but something covers it: an overlay, a toast, a cookie banner. Your click was fine; the page wasn't ready the way you assumed.
• TimeoutException — the wait's condition never became true. Wrong condition, wrong locator, or a genuinely slow app: three different fixes, and a bigger timeout is not one of them.

E   selenium.common.exceptions.ElementClickInterceptedException:
E     Message: element click intercepted: Element <button id="place-order">
E     is not clickable at point (640, 610). Other element would receive
E     the click: <div class="cookie-banner">...</div>

# The error printed the culprit. The fix is not a bigger wait —
# it is dismissing the banner, or asserting it is gone before clicking.

Framework noise

Frames from site-packages are scenery — fixtures, retry plugins and reporters add noise that means nothing. Your bug lives where your code meets the library, usually one frame.
