[Reproducer Required] onDownload: Using, and an error

Ui.Vision
1

I am really enjoying Kantu and have written a script to download photos from FB.

It works but the file names are annoying, so I wanted to rename the image files to the timestamp the photo was taken.

But… every time I try using onDownload I get the error
[error] until: download start expired!

What happens is the onDownload row runs, and it moves to the next row, where it hangs.

I have tried setting the second parameter to true, false and <<blank>>, but none of them work.

This is:

  • Windows 10
  • Chrome 71
  • Kantu 3.5.5
    • Storage mode: File system (on hard drive)

Here’s the script. To use:

  1. Go to a photo gallery
  2. Open the first photo in the lightbox by clicking on it
  3. Start the macro running
{
  "Name": "FB test with OnDownload",
  "CreationDate": "2018-12-19",
  "Commands": [
    {
      "Command": "storeAttribute",
      "Target": "//*[@id='fbPhotoSnowliftTimestamp']//abbr@data-utime",
      "Value": "myfilename"
    },
    {
      "Command": "onDownload",
      "Target": "${myfilename}.jpg",
      "Value": "true"
    },
    {
      "Command": "click",
      "Target": "//a[@data-action-type=\"open_options_flyout\"]/span",
      "Value": ""
    },
    {
      "Command": "click",
      "Target": "//div[@class='uiContextualLayerPositioner uiLayer']//a[@data-action-type='download_photo']/span/span",
      "Value": ""
    },
    {
      "Command": "click",
      "Target": "//*[@id=\"photos_snowlift\"]/div[2]/div/div[1]/div[1]/div[1]/a[2]/i",
      "Value": ""
    },
    {
      "Command": "pause",
      "Target": "2400",
      "Value": "2400"
    },
    {
      "Command": "echo",
      "Target": "${myfilename}",
      "Value": ""
    }
  ]
}

Is there a better approach?

Ideally I want to append the timestamp to the existing file name. The alternative idea I’ve had is to log the file name and timestamp to a CSV, and then write another (offline) program to rename the photos.

some questions:

  • if you don’t use onDownload, does it work then?
  • does the download actually start?
  • do you maybe see a dialog like this:

download%20multiple%20files

3
  • If I don’t use onDownload, it works.
  • Yes, the downloads work (I have downloaded 1000+ images)
  • The first run, yes. And I clicked ‘Allow’.

If you have a FB profile, please run the script to see the error happen.

Is there a bug in onDownload, or does it require specific conditions to work?

… I am not sure yet what is the right answer - we are debugging this currently :wink:

At the moment, we can not recreate the problems described here :sweat:

As a test, if you run the DemoDownload macro that ships with Kantu, does it work for you? In my test, all works ok and the downloaded files get renamed.

@pppppppepe I tried to run it, but the macro fails on the first command already. I guess I need to be at a specific start page for it work?

@admin Here’s a reproducible demo:

  1. Go to Redirecting...
  2. Run the macro provided above
  3. The result will be something like
    image

By contrast if you use the macro below, it works but does not rename the image files:

{
  "Name": "FB no x methods",
  "CreationDate": "2019-1-4",
  "Commands": [
    {
      "Command": "storeAttribute",
      "Target": "//*[@id='fbPhotoSnowliftTimestamp']//abbr@data-utime",
      "Value": "myfilename"
    },
    {
      "Command": "click",
      "Target": "//a[@data-action-type=\"open_options_flyout\"]/span",
      "Value": ""
    },
    {
      "Command": "click",
      "Target": "//div[@class='uiContextualLayerPositioner uiLayer']//a[@data-action-type='download_photo']/span/span",
      "Value": ""
    },
    {
      "Command": "click",
      "Target": "//*[@id=\"photos_snowlift\"]/div[2]/div/div[1]/div[1]/div[1]/a[2]/i",
      "Value": ""
    },
    {
      "Command": "pause",
      "Target": "2400",
      "Value": "2400"
    }
  ]
}

You can set this macro to run 30+ times and it will download 30+ images.

Hi :slight_smile:, I’ve copied and run the code in the example (https://github.com/A9T9/Kantu/blob/master/testmacros/demomacros/DemoDownload.json), but it doesn’t work.

Could you kindly help me please? I’m trying to understard how to rename downloaded files…

Ah, the screenshot explains the issue: It seems the website (Facebook?) is blocking EVAL on its website, just like Github. This problem is not related to OnDownload, but to storeEval.

For a workaround see 'unsafe-eval' is not an allowed source of script - #2 by ulrich - UI.Vision RPA - UI.Vision RPA Software Forum | Discuss RPA Automation, Selenium IDE and OCR API Text Recognition

Hi to all, I’m trying to use correctly the onDownload feature too. Currently in this way:

{
  "Command": "onDownload",
  "Target": "example.xls",
  "Value": ""
}

But if I set Chrome settings to automatically download files, Kantu doesn’t rename them.
What I’m doing wrong? Anyone could help me please?

Many thank & best regards,
Chris.

I got the same problem here. This error only shows up for certain website. I tried ulrich’s advise to run all storeEval in another tab, but it doesn’t work. Please help.

Every time I clear the browser history and data, all my data loses and you can simply visit hard drive recovery to get it solved on your system. I have got huge help from it.
