Cannot sync cloud data: "Unable to resolve path with root WinAppDataLocalLow (12)"

[flindeberg]

It seems that there are some issues with resolving paths for the Cloud Sync, at least for me.

I get the following in ~/Library/Application Support/Steam/logs/cloud_log.txt:

[2023-04-03 17:54:49] [AppID 892970] Unable to resolve path with root WinAppDataLocalLow (12)
[2023-04-03 17:54:49] [AppID 892970] Unable to resolve path with root WinAppDataLocalLow (12)

[2023-04-03 17:54:49] [AppID 892970] Unable to resolve path with root WinAppDataLocalLow (12)

And a bit further down:

[2023-04-03 17:55:01] [AppID 892970] Starting sync (up,AC Exit,)
[2023-04-03 17:55:01] [AppID 892970] Running AutoCloud on exit. Looking for new and updated files
[2023-04-03 17:55:01] [AppID 892970]     Skipping rule 0 because ResolvePath (WinAppDataLocalLow, IronGate/Valheim/characters) failed
[2023-04-03 17:55:01] [AppID 892970]     Skipping rule 1 because ResolvePath (WinAppDataLocalLow, IronGate/Valheim/worlds) failed

I assume I'm missing some environmental variable which points to where the WinAppDataLocalLow is on macOS?

~/Library/Application Support/unity.IronGate.Valheim-macOS-Custom/ is empty, and ~/Library/Application Support/Steam/userdata/<steam id>/892970/ contains one file remotecache.vdf, and the subdirectory remote does not exist.

I've tried launching with different environment variables set, from different locations, and from Steam "as a non-Steam game", but all give me the same log message in cloud_log.txt.

The game runs well though :-)

I see all my saved stuff correctly at https://store.steampowered.com/account/remotestorageapp/?appid=892970 (I used to play on Linux if that matters)

Hmm, curious. I have not seen the Unable to resolve path messages in stand-alone form in the cloud_log.txt file. That said, I did encounter some Failure to upload/download ...; likely manually removed-messages in one of the earlier log files, possibly related to me testing on two Macs simultaneously 🤔

Found a recent example of an exit-sync log (slightly altered) on my end:

Does your log have any additional entries after the Skipping rule 1-bit?

I created a world and character locally as well, just to try if that would jumpstart something, but it doesn't.

Do you have any ideas?

[timkurvers]

Hm, I wonder if the previous platform one plays on matters. I suppose there's three variants:

• Never played Valheim before
• Played Valheim Linux and have Steam Cloud saves
• Played Valheim Windows and have Steam Cloud saves

Seeing as I used to play Valheim Windows via CrossOver as well as Bootcamp, perhaps that makes it so the cloud syncing works even on this macOS custom build 🤔

Is there anything of interest in ~/Library/Application Support/Steam/userdata/<userid>/892970/remotecache.vdf?

[flindeberg]

Interesting. What ostype do you get @timkurvers ?

"892970"
{
        "ChangeNumber"          "0"
        "ostype"                "-75" // What does this mean?
        "IronGate/Valheim/characters/<remote-character>.fch" // Note the path!

        }
        # Some more local stuff (inc worlds)
}

Ah, I just notices something again, the "root" "12" might be connected to Unable to resolve path with root WinAppDataLocalLow (12).

Perhaps root number 12 does not exist on MacOS, for example. But does on Linux and Windows.

[flindeberg]

I think I know what is going on now. For some background see https://partner.steamgames.com/doc/features/cloud

I will verify and hopefully close this issue tonight, and write an MR which explains the shenanigans properly.

[timkurvers]

Interesting. What ostype do you get @timkurvers ?

• ostype is the same: -75.
• All my entries have "root" "0".
• None of the paths are prefixed with IronGate/Valheim.
• Have a few entries that have differing syncstate and/or persiststate but I think that may be related to some files that are not syncing properly due to being logged out of Steam while playing the game 😅

Oh, that sounds great! Thanks for looking into it 👍

[flindeberg]

So, TLDR. The paths to where Valheim saves stuff seems to have been changed since I played last on Linux.

This mean I had to log in on that computer and mark all saves as "Cloud Save". This moves them into the correct root.

You can double check at https://store.steampowered.com/account/remotestorageapp/?appid=892970, the "Folder" column should be blank if the correct root is used. If think it said WinAppDataLocalLow when it didn't work.

I cannot recreate the issue with new chars, and the issue appears for chars created before version 0.209.8.

The specific changelog:

Steam Cloud:

- Cloud save files will now be stored in Steam/[YourIDNumber]/892970 instead of AppData
- Local files will now be stored in “worlds_local” and “characters_local” under AppData and no longer be synced to cloud to -avoid sync conflicts and dataloss when using multiple accounts on the same machine, and when using dedicated servers.
- Files still in the old file structure will be moved to the Steam Cloud or new local folder when used and a backup will be kept
- Worlds’ save files can now be renamed and will load correctly
- Large worlds (300mb or bigger) should now sync correctly
- Maximum Cloud storage for Valheim has increased greatly, thanks Valve!

I'll create a PR for a small change.

[flindeberg]

Added #19 and I consider this fixed now so I'll close it.
