I have a problem when working with iframe using Robot framework and Selenium2Library. It throws error:

WebDriverException: Message: unknown error: unhandled inspector error: {"code":- 32000,"message":"Cannot find context with specified id"} (Session info: chrome=55.0.2883.87) (Driver info: chromedriver=2.25.426923 (0390b88869384d6eb0d5d09729679f934aab9eed),platform=Windows NT 6.1.7601 SP1 x86_64)

My test code is:

Fill In Description ${description} Wait Until Element Is Visible ${FRAME} 40 Select Frame ${FRAME} wait until page contains element ${IFRAME BODY} Click Element ${IFRAME BODY} wait until page contains element ${IFRAME BODY} Clear Element Text ${IFRAME BODY} wait until page contains element ${IFRAME BODY} Input Text ${IFRAME BODY} ${description} Unselect Frame

It fails in step Input Text ${IFRAME BODY} ${description}

Btw I reuse this keyword for more pages where this iframe occurs but it fails only in once exact case - but the html code is the same for all the iframes, so really dont understand why it works just sometimes..

Will be glad for any help.

  • what does ${IFRAME BODY} represent? By the name it sounds like an iframe element or the body inside an iframe, in which case I don't understand why you're trying to input text into an iframe (versus an input element). Commented Jan 2, 2017 at 15:53
  • The structure in html is: <iframe><html><body></body></html></iframe> and the <body> element is the one which stands for "input field", there is no other element inside..thats why I am trying to input into <body> element...and as I mentioned, it works in 2 cases, but does not work in 1 case...

    what do you think should happen when you input text into something that isn't designed to take text? Commented Jan 2, 2017 at 16:18
  • well, obviously it types the text into the body element - really works for 2 out of my 3 cases (pages with iframes)...just in one it does not, and I really don't know why because the code behind that is the same.. Commented Jan 2, 2017 at 16:30
  • I just had the same error message on a test script. The exception is thrown on this line: WebDriverWait(driver,10).until(EC.presence_of_element_located((By.XPATH,myxpath))) Similar to what @neliCZka is reporting, it sometimes hangs on this line, which is re-iterated several times, but most other times, it works fine. I wish I knew how this error is different than, say, an "element not found" error or a "timeout" error. Commented Jan 4, 2017 at 1:21

This issue seems to be reemerging in chromedriver, latest one being: https://bugs.chromium.org/p/chromedriver/issues/detail?id=2198

According to this ticket can be fixed in two ways:

  • switch to chromedriver version which does not have this issue
  • add wait after switching to frame

So I had to change the code like this to work in other frame:

Log comment ${comment} wait until element is visible ${RICH TEXT AREA} 40 sleep 1 click element ${RICH TEXT AREA} Wait Until Element Is Visible ${FRAME} 40 Select Frame ${FRAME} wait until element is visible ${IFRAME BODY} 20 input text ${IFRAME BODY} ${comment} Unselect Frame

${IFRAME BODY} is still //body in Iframe and surprisingly it inputs the text all the time now... And unfortunately it does not work without sleep :( But with sleep it works..

What change did you make? I'm getting the same error message with puppeteer against Chrome, but I this code is a wall of text to me. Thanks!
I dont know really, I just added implicit wait (sleep) and I did some clicking into the element in which the iframe exists before I access the iframe itself. It is also possible that it started working due to higher version of chrome driver.
