Note overread on buildoutput and complete absence of contentroot field. This is basically the example vdf file from Steam docs so I'm surprised to have his this error. Tried changing line endings to CRLF and LF and it made no difference.

Interestingly I had the exact same error using vdf package and jumped to this one when I noticed there was a new alternative. I hope my input is not somehow malformed?

Alright, it seems to be choking on this line:

  "buildoutput" ".\output\"

I guess it's misinterpreting the final \ as an escape character?

Check out the "simple build script" example here: https://partner.steamgames.com/doc/sdk/uploading?language=english

"AppBuild"
{
        "AppID" "1000" // your AppID
        "Desc" "This is a simple build script" // internal description for this build

        "ContentRoot" "..\content\" // root content folder, relative to location of this file
        "BuildOutput" "..\output\" // build output folder for build logs and build cache files

        "Depots"
        {
                "1001" // your DepotID
                {
                        "FileMapping"
                        {
                                "LocalPath" "*" // all files from contentroot folder
                                "DepotPath" "." // mapped into the root of the depot
                                "recursive" "1" // include all subfolders
                        }
                }
        }
}

Even this is output incorrectly:

{
  AppBuild: {
    AppID: 1000,
    Desc: 'This is a simple build script',
    ContentRoot: '..\\content\\" // root content folder, relative to location of this file\n\t',
    Depots: {
      '1001': { FileMapping: { LocalPath: '*', DepotPath: '.', recursive: 1 } }
    }
  }
}
