I get a 9999 error when uploading .zepetopackage file in Zepeto Studio.

If you get a 9999 error in ZEPETO Studio when uploading the .zepetopackage file generated after building your World, try the following three methods.

Go to Unity Hub > Installs > 2022.3.34f1 > Add Modules and check if all the required modules are installed.

The required modules are the following:



Mac

Windows

Also, click the login menu next to the 'Publish' button and make sure that 'Target Platforms' is set to 'All'.

If all required modules are installed, click the Publish button to rebuild your world.

Once the build is complete, open the project folder > Build > ZEPETO.Script folder to verify that all platform files have been generated.

The required platform files are:

Upload the generated .zepetopackage file to ZEPETO Studio.

For more details, please refer to the guide below:



In Windows environments, the length of the path name can affect package builds.

If there are files or folders with excessively long names within the Assets folder, a 9999 error may occur when uploading to ZEPETO Studio.

Ensure that file names do not contain spaces or special characters.

Rename files to concise names like “abc.jpg” and rebuild the project.

Even if the folder names are automatically generated from the Unity Asset Store, please rename them to shorter names.



If you get a 9999 error even though you have installed all the required modules, try the following method.
