Roguebook: How to Fix the GameboxEngineService ERROR

This is the moment before the first battle starts:

The battle does not load properly, and following screen appears:

The error message states that the GameboxEngineService encountered an error at initialization, and that you should check the logs for more information:

ERROR GameboxEngineService:0 - Could not initialize GameBox (-4): check logs in %USERPROFILE%\AppData\LocalLow\Abrakam Entertainment SA\Roguebook\gamebox_logs

If you check the logs, you will see that several game files have the same id:

Multiple files match the format for script of entity id 9:
    C:\Applis\Steam\steamapps\common\Roguebook\Roguebook_Data\StreamingAssets\GameBoxResources\cards_scripts\0009.blood_gift.xlb
    C:\Applis\Steam\steamapps\common\Roguebook\Roguebook_Data\StreamingAssets\GameBoxResources\cards_scripts\0009.grim_siphon.xlb

There are actually 67 problematic files, and it is possible to remove the duplicate ids with Python[gist.github.com]. However, you will encounter other kinds of error afterwards, because the files have not been updated in a long time. For instance:

[email protected],07 COMPILATION ERROR [GameBox::EntityInfoLibraryServiceImpl::readEntityInfoLibrary@48] Error(s) while reading entity with id 94 from json:
[...]
0x0000000c: Semantic Error - Could not find getter 'bearer' on type 'entity<creature>' 
[...]
 line 2:
    if (castToDeckCard(event.target.killer).heroType == this.bearer.heroType) INDENT
                                                             ^

So what you want instead is to fetch the latest build of the game!

You can force an update of your game by forcing download_depot of the public branch.

To do so:

• Open Steam’s console, e.g. by typing Win+R and then:
  steam://open/console
• Write down the manifestID of the latest build, which you can find on SteamDB[steamdb.info].
  
• Download the game content with:
  download_depot 1076200 1076201 manifestID

  For instance, on the day of the game release (June 17, 2021):

  download_depot 1076200 1076201 7529912476901754664

  NB: The depotID for Windows is 1076201, but for Mac, it is 1076202, and for Linux: 1076203.

• Copy steamapps\content\app_1076200\depot_1076201 to steamapps\common\Roguebook
  which, in case you need a more detailed process, means to:
• Rename Roguebook to Roguebook_old in steamapps\common\
• Copy depot_1076201 from steamapps\content\app_1076200\ to steamapps\common\
• Rename depot_1076201 to Roguebook in steamapps\common\

If you want to update your build in the future, check the history of manifestIDs[steamdb.info] for game updates, or the history of changes[steamdb.info] for a more verbose output.

Tadaaa!

Caveat: do not ask Steam to verify the game files, or you will be back to square one.
