[instagram][error] FilenameFormatError: Applying filename format string failed (TypeError: unsupported format string passed to NoneType.__format__)

[Miroslav-Cetojevic]

I could've sworn that this error popped up overnight. Here's my conf for instagram:

    "instagram": {
      "username": "username",
      "password": "randomstring",
      
      "directory": ["{category}"],
      "filename": "{post_shortcode}_{num:>02}_by_{username}.{extension}",
      
      "sleep": 1.0,
      "sleep-request": 10.0
    },

Command line:
gallery-dl -o directory=[] https://www.instagram.com/someaccount/ -d "C:\Path\to\dest"
It will download for a bit, before the error shows and ends the program. There's no reason for this to happen, as far as I can tell. Can I fix this? If so, how?

{num} is not defined for posts with only 1 image/video, but it still tries to apply >02 to the missing value and fails. You could either use a ? or conditional filenames:

    "filename": "{post_shortcode}{num:?_//>02}_by_{username}.{extension}",

    "filename":  {
        "locals().get('num')": "{post_shortcode}_{num:>02}_by_{username}.{extension}",
        ""                   : "{post_shortcode}_by_{username}.{extension}"
    }

Should the default filename setting be updated?
