问题
I am trying to access value 12345 from span element on a target webpage which looks like this:
<span id="[long-dynamically-generated-unique-id]:StaticFixedString"> 12345</span>
[long-dynamically-generated-unique-id] is unique id which changes every time I visits the website. So I want to base my selector on :StaticFixedString. I am able to do this as follows:
amt = driver.find_element_by_xpath(u"//*[contains(@id, 'StaticFixedString')]")
At least, in debug mode, I am able to see amt in Variables window of PyCharm as follows:
When I click on triangular arrow in front of the variable to expand its properties, the taskbar icon of chrome window opened by selenium starts flashing. Variable window of PyCharm shows Collecting data... as follows:
After some time, it shows something like this:
It then logged following error:

Why is this happening? What I am missing?
Edit
The target size has right click disabled. Can this be an issue?
