I am trying to publish my app but I am getting this error when I click publish

I am not getting any specific error I also checked the console.log nothing I can find

I am not using mapps code:push

I am using Vercel to host my app

and I using custom url for my feature

Do I have to upload my code with Monday code?

What are steps?

Do I have to first submit app for review and then I am allowed to publish my apps?

How that’s works, lil bit confuse here
