The problem with StaleElementReferenceException is usually that you look up elements on a page, hold them in a variable and then do some interaction that causes the page to change or reload.
It seems you are doing exactly this: the
list variable is initialized first, then you loop through it and then you click a search button multiple times, which probably updates the page. This makes the
list variable invalid and will cause the exception if you try to interact with any of it's elements.
What might work in this case is if you do the following:
- Hold a variable of the amount of items in the list (currently
a, it's recommended to have more descriptive variable names)
- Loop through all values between 0 (inclusive) and
a with index
- Within each iteration, initialize
list again and take element
- Proceed to do the same as what you are currently already doing inside the loop with element
