[Bug]: Development store preview on Plus Sandboxes

[bastos71]

Please confirm that you have:

• Searched existing issues to see if your issue is a duplicate. (If you’ve found a duplicate issue, feel free to add additional information in a comment on it.)
• Reproduced the issue in the latest CLI version.

In which of these areas are you experiencing a problem?

Extension

Expected behavior

When activating the "Development store preview" feature in an app extensions panel, new draft features should appear in the Theme Editor given by the command npm run shopify app dev

Actual behavior

On Plus Sandboxes, this does not work, npm run shopify deploy is mandatory to see new features.
It's annoying when you have to work on features linked to Plus only features (like B2B for instance)

Verbose output

➜ npm run shopify app dev -- --store=b2b-accounts.myshopify.com --verbose

> shopify-b2b-accounts-app@1.0.0 shopify
> shopify app dev --store=b2b-accounts.myshopify.com --verbose

2024-04-17T10:20:04.603Z: Running command app dev

Reproduction steps

1. Run the following command to any Plus Sandbox store :

npm run shopify app dev

2. Add a new component in the extension

3. Command output shows the component is uploaded

4. It does not appear in the Theme Editor, even after reloading the page

hi @bastos71 thanks for reporting this issue and for your patience 🙏 first -- do you have the correct permissions to use dev sandbox stores for this plus merchant?? you'll need a staff account

next, can you share all the verbose logs of app dev, including when you modify a theme app extension?? i only see the beginning of the logs in the issue description

lastly, can you also confirm your folder structure matches the expected structure of an app?? if app dev isn't run in the correct directory, your changes may not be picked up while developing

thanks for your help as we investigate your issue!

Hello @mgmanzella !

This Shopify Plus instance is a sandbox one I created from our partner dashboard, so I guess there wouldn't have any issue about right access ?

For the logs, I voluntarily gave only the first lines for several reasons :

• full log was really long 😬
• it was not different from the log I get with a classic Shopify instance

If you still want full log, let me know, and I'll try to send it 👍

For the folder structure, my app was not created with shopify cli, but everything works with a classic Shopify instance, so I guess the problem should not come from there ?

If you still want full log, let me know, and I'll try to send it 👍

yes pls! and make sure it includes logs of when you're modifying your theme app extension. if you're having trouble sending it over a github issue, feel free to DM me in the partners slack @Morisa Manzella

yeh looking at your account you're the owner so there shouldnt be any issues. does app dev work for a non plus development store?? is that what you mean by a classic Shopify instance??

Hi @mgmanzella, just to add: for me it works when I create a plus sandbox store directly, but it doesn't work if I create a plus sandbox organisation and then create plus sandbox stores within the org.

hello @mgmanzella , here is attached the full log I get : shopify-app-dev.log
By running :

npm run shopify app dev -- --store=b2b-accounts.myshopify.com --verbose > shopify-app-dev.log

(just tried again to be sure with a new "Testing component" extension and the same behavior occurs, working on a development store but not on a Shopify Plus sanfbox)

For your second question : yeah exactly I meant a non plus development store 🙂

thanks for sharing this info! we'll investigate and let you know if we need more information 🙏
