'NoneType' object is not subscriptable

• Snapchat Downloader Version: 2.0.1
• Python Version: 2.7.16
• Operating System: Mac OS 10.15.7 (Catalina)

Description

I was trying to download stories as usual from my list but I now get an error message 'NoneType' object is not subscriptable. It was working 24 hours ago. Normally, when I type the command, it just starts saving stories from my list.

What I Did

I typed:
snapchat-dl -u -i Usernames0.bat -P SnapDownloads

This is what I got back:
Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/3.10/bin/snapchat-dl", line 8, in <module> sys.exit(main()) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/snapchat_dl/app.py", line 58, in main download_users(usernames) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/snapchat_dl/app.py", line 53, in download_users downlaoder.download(username) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/snapchat_dl/snapchat_dl.py", line 131, in download stories, snap_user = self._web_fetch_story(username) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/snapchat_dl/snapchat_dl.py", line 95, in _web_fetch_story stories = util_web_story(response_json) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/snapchat_dl/snapchat_dl.py", line 91, in util_web_story return content["props"]["pageProps"]["story"]["snapList"] TypeError: 'NoneType' object is not subscriptable

Please help, thank you.

Chatgpt told me to change this code:

Replace this code in snapchat_dl.py:
C:\Users\USER\AppData\Local\Programs\Python\Python**\Lib\site-packages\snapchat_dl

            def util_web_story(content: dict):
                if "story" in content["props"]["pageProps"]:
                    return content["props"]["pageProps"]["story"]["snapList"]
                return list()

With:

            def util_web_story(content: dict):
                story_data = content["props"]["pageProps"].get("story")
                if isinstance(story_data, dict) and "snapList" in story_data:
                    return story_data["snapList"]
                return [] 

Seems that they changed the json for users that don't have current stories.

Thanks for your suggestion. I made the change but it still gives me the same error message

TypeError: 'NoneType' object is not subscriptable

I tried asking ChatGPT to fix the code for me and tried 5 different versions but none of them resolved the issue. This is only a problem when I ask snapchat-dl to use -i BATCH_FILENAME.

Using snapchat-dl -u -i Usernames0.bat -P SnapDownloads, once a username with no stories is encountered, the list stops there. I want it to keep moving to the next username.

When I type multiple usernames manually, then the ones that don't have stories still result in an error message (as expected), but it is at least able to move on to the next username until the list is exhausted. For example, I just copy paste this into my console:

snapchat-dl username1 snapchat-dl username2 snapchat-dl username3 snapchat-dl username4 snapchat-dl username5

(with linebreaks in between each snapchat-dl, not sure how to put that here)

Weird it runs fine for me, but I use a powershell script:

while($true){
snapchat-dl USERNAME1 -j 1
snapchat-dl USERNAME2 -j 1
snapchat-dl USERNAME3 -j 1
etc
Start-Sleep -Seconds (Get-Random -Minimum 30 -Maximum 60)
}

I am getting the same issue, perhaps @skyme5 can look into this whenever he gets the time.

[quietsecret123]

Weird it runs fine for me, but I use a powershell script:

Thanks, @promers, for sharing your code. I changed mine to match yours (copy-pasted it), but unfortunately, it still doesn't work for me. ChatGPT hasn't really done much help either. I guess @cheese529 and I will just have to wait for now until @skyme5 gets a chance to update the code.

For now, I can make do with manually entering 20 usernames at a time.

same issue

[Dreamscape-419]

I just recently started receiving this same error. I have a task that downloads 8 different usernames and now It fails after the 3rd username every time.

[Dreamscape-419]

Chatgpt told me to change this code:

Replace this code in snapchat_dl.py: C:\Users\USER\AppData\Local\Programs\Python\Python**\Lib\site-packages\snapchat_dl

        def util_web_story(content: dict):
            if "story" in content["props"]["pageProps"]:
                return content["props"]["pageProps"]["story"]["snapList"]
            return list()

With:

        def util_web_story(content: dict):
            story_data = content["props"]["pageProps"].get("story")
            if isinstance(story_data, dict) and "snapList" in story_data:
                return story_data["snapList"]
            return [] 

Seems that they changed the json for users that don't have current stories.

This change seemed to fix the issue for me. Thanks

thanks but didnt work with me

thanks but didnt work with me

I made a fork / pull request with the bug fixes, you can try it

@ExplorerNL your are the legend; its working now Thanks a lot, man

This didn't work for me, unfortunately. I tried downloading your new snapchat_dl.py file and replaced the original one by @skyme5, but I still received the same error message:

May I ask, what command do you type into console? The command I use is:

snapchat-dl -u -i Usernames0.bat -P SnapDownloads

SnapDownloads is the name of the folder I store them in, and Usernames0.bat is just a list of snapchat usernames for snapchat-dl to download from.

Thank you!

Hey!

I use this command:
