  1. I am unable to start the recording in the Web UI node, get the following error message. Image description
    Perform the following steps.
    1. Navigate to Chrome extensions(chrome://extensions/) and check if the JIFFY extension is enabled.
      • If not enabled, enable the same.
      • Restart the Google Chrome browser and start the recording.

    2. If after enabling the Chrome extension the error persists, check if the file ChromeUILearnNativeMessagePump.exe exists in path C:\jiffyservice\CommonFiles\UILearnChromePlugin\host.
      • If a backup file(ChromeUILearnNativeMessagePump_backup.exe) exists, rename the file to ChromeUILearnNativeMessagePump.exe.
      • Restart the bot after the changes are made and start the recording.
    3. If error persists, replace the Jiffy extension.
      • Enable the developer mode if it is not enabled, refresh the Chrome://extensions page.
      • Remove the current jiffy extension.
      • Drag the Jiffy_chrome_extension.crx file from C:\jiffyservice\CommonFiles\ChromeExtension and drop it in the chrome extension section of the Google Chrome browser.
      • Restart the Google Chrome browser and start the recording.
  2. I am unable to record using JiffyUILearn when I hover the mouse cursor on the UI element to be recorded and press CTRL key on keyboard nothing happens. The UI element is not getting highlighted in red color, and listed.
    Check if the developer mode is enabled for chrome extension, if not enable the same and restart the browser. Image description
  3. When executing Web UI node that has web table extraction, I get the error “Element Not Found“. Image description
    This error can occur due to multiple reasons:
    1. The search result is empty: Check if the search result on the website fetches any data. Search manually with the same inputs and ensure data is fetched. Else change the inputs for which data is available in the search result.
    2. Add a step for Delay using predefined function Delay In Seconds, provisioning time for data to load completely on the webpage before the element is read.
  4. When executing Web UI node that has web table extraction, I get the error “List index out of range”. Image description
    This error can occur due to multiple reasons:
    1. Index position given is incorrect: Check the row/column number matches with what you have recorded, for example, three columns are recorded but the column number given is four, this error can occur.
    2. Add a step for Delay using predefined function Delay In Seconds, provisioning time for data to load completely on the webpage before the element is read.
  5. During execution of Web UI node with Image/Text Recording, I get an error “Task cannot be executed. Current screen width: 1536 or Height 864 is different from the Learned Width 1920 or Height 1080”. Image description
    This error occurs when the resolution of your machine is different from the resolution while the elements were recorded.
    Check if the layout is set to 100% in the display settings. (Refer the following Snapshot).
    Check the Display resolution is the same as mentioned in the error for the learned element Width 1920 or Height 1080. If not change the values.
    If the error persists, change the resolution to 100% and re-record the element. Image description
  6. When executing the Web UI node, I get an error in step data that, "Given row number one is more than available data rows zero.". Image description
    This error occurs when the row number given is not present in the result set.
    Check if the search result on the website fetches any data.
    Search manually with the same inputs and ensure data is fetched, else change the inputs of the automation for which data is available in the search result and provide a row number that has data.
  7. I need to add a few more elements to an existing WebUI node. When I start recording, I am highlighting the element and pressing the CTRL Key but it is not getting recorded. Image description
    Ensure Screen in which you want to add elements is selected in the UI Learn dialog box.
