When uploading a custom character to Flow Studio, the error message appears.

This error typically occurs when you're using an outdated validation add-on or when you've modified files after completing validation. To resolve this:

1. Remove the previously generated '01_wonder_studio_character_data' folder.
2. Download and instal the latest version of validation add-on.
3. Validate your character through the add-on, and do not modify the character or metadata.json files after validation.
4. Upload the newly generated files to Flow Studio.

Here's a direct link for downloading the newest add-on version: Install the Validation Add-on
