Parse error: source must be an array. See console logs for more info.

[Giulia Nicole Pernice]

HI, we have a "global" Tokens set and two other sets: "Dark-Thme" and "Light-Theme".

We select "Multiple Files" when exporting from the Tokens Studio plugin (pro license).
However, when trying to import in the configurator, we get a:
"Parse error: source must be an array. See console logs for more info." error.

The log shows just the same, with several:

Also thene.json looks empty, while all other files have data.

From our slack conversation:

The project where the error is found

This is missing content in the $themes.json, as well as source not being %themeTokenSets% (special thing for the configurator to understand what to do).

Fixed project here

We should give better warnings to the user when:

• $themes.json is invalid
• SD Config does not have proper source %themeTokenSets% (maybe even fix that forcefully)
