My Home page is 404 after import theme from zip file

[huongpho]

Hello,

I'm experiencing an issue where my home page shows a 404 error instead of loading correctly, both in the customize view and the live view.

Here's what I've done:

1. I have a production environment and created a new theme, made edits to it, and exported the theme as a zip file.
2. I then set up a development environment, imported the zip file, and now the home page redirects to a 404 error. For clarification, I imported the original theme from the production shop and it worked fine after manually copying the navigation.

Can anyone suggest how to resolve this?

I found the following log in the console:

main.js:907 Uncaught TypeError: Cannot read properties of null (reading 'addEventListener')
    at StoreHeader.bindEvents (main.js:907:23)
    at new StoreHeader (main.js:892:10)
    at main.js:1086:16

And in the network log, loading my page returns a 404 code.

I would really appreciate any help. Thanks!

hey, @huongpho I have checked your theme.
Your theme has missed the index.json file in your theme therefor it makes 404 page on the home.

I managed to resolve the issue and wanted to share my experience for anyone facing the same problem:

• My original theme included an index.json file, and the exported files also contained an index.json file.
• However, during import, the index.json file wasn't imported due to an error (a missing source for a video clip).

To fix this, I manually added the missing video clip, created a new index.json file, copied the content over, and now everything is working.

Thanks for your help!
