How to access elements in a popup modal iframe using selenium and python

Viewed 1024

I am trying to click on an input that dynamically appears when clicking another button on the page. I can see that the input is contained in an iframe tag and have tried to use selenium with browser.switch_to.frame() (where browser is my webdriver object) Whether I use the frame's id or the frame's object (which selenium can find) or the frame's index, I get the error message below I have tried to wait to insure that the popup is visible and active on the webpage. I can switch frames to the other 4 iframes in the page without issue.

My current round of code looks like this:

        time.sleep(5)
        frames = self.browser.find_elements(*(By.XPATH, '//iframe'))
        if frames[4].is_displayed(): 
            print("frame is displayed")
        wait(self.browser, 10).until(EC.frame_to_be_available_and_switch_to_it(frames[4]))

Here is the element (without opening and closing tag):

"iframe id="QuickPopupIframe" style="width:100%;height:100%;border:none" src="../Reference_Priority/Reference-Priority-QuickSelector.aspx?Target=ctl00_PageContent_PriorityCode&amp;Formula=MVufX1PgieR56FP4ih%2fB7DmXUWVgW2K7F61ffR%2bNCiA%3d&amp;IndexField=SYGQ1ZIIAsXlmKS73s9dbg%3d%3d&amp;EmptyValue=VMGNuzfo24fWSZTXc2WIC9A6qT5R5C0gEgrksjxUk3M%3d&amp;EmptyDisplayText=PsbWe8ErKzHmHOECyYwb2dswos6g1dh5dGzsQ%2fORFos%3d&amp;Mode=F7zc4UXA5KrLE%2bF%2b%2fEj%2bx335yFqXWI8TM9%2fceff20ZA%3d&amp;RedirectStyle=pIzLWXDCgKbu9KF0MLvFEg%3d%3d"></iframe"

Here is the Error Logged:

self = <selenium.webdriver.remote.errorhandler.ErrorHandler object at 0x036DC628>
response = {'status': 404, 'value': '{"value":{"error":"no such window","message":"no such window\\n  (Session info: chrome=81.0....\n\\tBaseThreadInitThunk [0x76FE8494+36]\\n\\tRtlAreBitsSet [0x77424328+136]\\n\\tRtlAreBitsSet [0x774242F8+88]\\n"}}'}

Try driver.switch_to.frame instead of frame_to_be_available_and_switch_to_it.

time.sleep(5)
frames = wait(self.browser, 10).until(EC.presence_of_all_elements_located((By.XPATH,"//iframe")))
if frames[4].is_displayed(): 
    print("frame is displayed")
    #wait(self.browser, 10).until(EC.frame_to_be_available_and_switch_to_it(frames[4]))
self.browser.switch_to.frame(frames[4])
