Downloader throws SyntaxError despite running successfully in the past

[Rabbidking]

The .exe was working fine until recently, where for some unknown reason, I get this error upon launching it (some stuff censored out just in case):

Steam path: "my Steam path" SteamID: "my Steam ID" Steam grid path: "my grid path" Total packages in library: "number of packages" Retriving package details Loading packageinfo.vdf Traceback (most recent call last): File "missing_cover_downloader.py", line 580, in File "missing_cover_downloader.py", line 551, in main File "missing_cover_downloader.py", line 112, in get_missing_cover_app_dict File "missing_cover_downloader.py", line 197, in get_package_details File "missing_cover_downloader.py", line 214, in load_packageinfo File "vdf.py", line 524, in packageinfo_loads File "vdf.py", line 375, in binary_loads_at SyntaxError: Unknown data type at index 9680: b'\x19' [5932] Failed to execute script missing_cover_downloader

Again, all I've done is download the main executable/JSON package from the Releases tab. I have neither modified any files nor rebuilt anything from source. It used to work with no problems, but suddenly this error has been popping up, and I'm unaware of any fixes. I also tried deleting my packageinfo.vdf file from my appcache and letting Steam restore it on a restart, but that didn't seem to do anything.

Having the same identical issue

[Jonius7]

It's because Steam changed its package format. See details here: https://github.com/SteamDatabase/SteamAppInfo

So that would mean editing vdf.py. Unfortunately I have no idea how to understand deserialising stuff at the byte level.

[Jonius7]

Well, turns out I was able to understand enough and added 2 lines of code, which fixed the syntax error and allowed me to import 235 images into my Steam library.

The fix is on my fork if the pull request hasn't been accepted yet.

Do you think you could also supply a windows executable as in this repository ? Wouldn't know where to start compiling that. Thanks

You can download the files from his branch and run it like the readme says :)

Speaking of which, the readme could use a little update, steam is at v1.0.2 now, so that pip install special note shouldn't be needed.

I have added an unofficial exe to the "pre-release" (used PyInstaller btw if you were wondering) https://github.com/Jonius7/steam-missing-covers-downloader/releases/tag/new-format-fix

it says it's missing python38.dll when trying to launch it.

it says it's missing python38.dll when trying to launch it.

Fixed it, needed to add --onefile flag to PyInstaller to package all the extra files into the .exe

Hey, newbie here, would love to find a fix for this but this is happening again when trying to run the .exe on Jonius7's March 2021 version of the program as well, would it be possible to have a fix? Here's my error log (the exe closes itself)

Steam path: c:/steam SteamID: [redacted] Steam grid path: c:/steam/userdata/[redacted]/config/grid Traceback (most recent call last): File "missing_cover_downloader.py", line 580, in File "missing_cover_downloader.py", line 551, in main File "missing_cover_downloader.py", line 109, in get_missing_cover_app_dict File "missing_cover_downloader.py", line 221, in get_owned_packages KeyError: 'Licenses' [17920] Failed to execute script missing_cover_downloader

I'd try to fix it but my python skills are next to none, thank you!

[Jonius7]

I've had a look and unfortunately I'm not sure how to fix it @wynick27 any idea? it seems for line 221 of missing_cover_downloader.py:

return list(int(pkgid) for pkgid in local_config['UserLocalConfigStore']['Licenses'].keys())

Licenses doesn't exist in the dictionary anymore

[Jonius7]

I've found that changing it to

return list(int(pkgid) for pkgid in local_config['UserLocalConfigStore']['Software']['Valve']['Steam']['apps'].keys())

works for a bit but then gets stuck on load_appinfo

File "C:\Users\Jason\Downloads\steam-missing-covers-downloader\vdf.py", line 375, in binary_loads_at
    raise SyntaxError("Unknown data type at index %d: %s" % (idx-1, repr(t)))
SyntaxError: Unknown data type at index 20: b'\x85'

[wynick27]

It seems valve changed license info store location. Now licenses are stored in licensecache rather than localconfig.vdf. It's also encrypted with random number stream generated from user id.

[wynick27]

@Jonius7 I've added parsing function for new licensecache format. Now it should work correctly.

[Dsp211]

Will test this new version right now, thank you both so much!

[Jonius7]

Still seems to be running into the same error @wynick27 :

[Jonius7]

@wynick27 Bump for update, something in the appinfo.vdf isn't able to be read.

I think I found some info here: https://github.com/SteamDatabase/SteamAppInfo

[Jonius7]

I have found a fix to accomodate the new format, quote my old post, since the circumstances are the same:

Well, turns out I was able to understand enough and added 2 lines of code, which fixed the syntax error and allowed me to import 282 images into my Steam library.

Also fixed the asyncio RuntimeError: Event loop is closed error that happens at the end of downloading.
