SDKBOX IAP IOS issue

One of our developers trying to add SKDBOX to his project, added all frameworks and initialization/purchase code.

When launching app getting error:

SDKBOX_CORE :Failed to find local config file in bundle and bundle/res.

Is there some issue with downloaded sdkbox(corrupted) or wrong initialization on our side, maybe you can advice what to check?

First check Xcode, make sure sdkbox_config.json is in Resource folder for c++ project and res folder for js project.

If everything looks correct, check the build step tab and make sure it’s been copied to the package.
