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.

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
