Error "int java.util.List.size()" occures when filnalizing a draft submission on Kobo Toolbox. How do I send the drafts?

Hi @Farkhad_Tutkabaev

When you get a chance, please introduce yourself here. I'd also encourage you to add a real picture as your avatar because it helps build community!

It seems Kobo Toolbox may not offer an option to replace an existing form to allow downloading the corrected version and finalizing drafts, but I could be mistaken. If it's a minor adjustment, you could try manually replacing the XML forms on your device, which should then allow you to finalize the forms.
Let us know if you're still seeking a solution or need any assistance on how to do that.

Could you also share your solution? It might help other users who have similar problems.
