[Bug]: shopify theme dev is losing track of the development theme

[karreiro]

In which of these areas are you experiencing a problem?

Theme

Expected behavior

When users run shopify theme dev, a development theme should be created and assign as [yours] (your development theme should never be re-assigned).

Actual behavior

When users run shopify theme dev, the development theme seems to be re-assigned and in some contexts the CLI is election even non-development themes.

This has been a huge pain all day today. Not sure what's going on, but its made it basically impossible to reliably build things with the session re-assignment happening

Getting the same issue, started a few days ago. This problem has come up in the past and was resolved with an update. It's really frustrating. When running shopify theme dev my dev code is being run with the primary published theme, instead of the development theme.

The only way I can keep working is to do so within the theme editor.

[DreamyTalesPAN]

Still having the same issue since a couple of days. Tried to delete the development theme with shopify theme --delete and re-run shopify theme dev in an incognito tab but no success so far.

Here's how I'm working around it:

shopify theme list

Find your development theme in the list

shopify theme delete -t {ID of your development theme}

Run shopify theme dev and it should use a new development theme instead of the live theme.

Agree this whole issue has been a pain in the a**. Shopify pushed a new CLI update today which now shows a new warning:

Warning: Could not find ts-node at /opt/homebrew/Cellar/shopify-cli/3.59.0/libexec/lib/node_modules/@shopify/cli/dist/index-e6f8190d.js. Please ensure that ts-node is a devDependency. Falling back to compiled source.

@karreiro emailed you a few examples of this - came here to find you've already flagged it!

appreciate all your help here

another example: #3794

[karreiro]

Thank you for sharing that context in the email, @davidhollenbeckx! That not only helps the team understand the issue itself, but it also helps us understand how developers use CLI in their workflows.

For anyone experiencing this problem, you can adopt the following steps as a temporary workaround:

• Run shopify theme push -u -t <name_of_your_dev_theme> to create a new theme
• Run shopify theme dev -t <name_of_your_dev_theme> to force the CLI to use that specific theme in the development server

As soon as we get this fixed, we will update this issue.

Thanks everyone for reporting this problem.

Thank you, everyone, for reporting this problem and providing details.

This issue has been fixed by #3809, so upgrading to the latest release (3.59.2) fixes this problem.

@karreiro Using v3.59.2, I am continuing to see theme mismatch problems. Not sure if this is the same issue or something new. The correct dev theme is usually loaded when first running shopify theme dev; however, when refreshing the page, it then swaps between the live theme and the dev theme on each subsequent reload.
The full command being used is: shopify theme dev --live-reload full-page.
I can provide a video or more details via DM, if that's helpful.

@karreiro This is definitely not fixed. See here: https://shopifypartners.slack.com/archives/CKQTKDZV2/p1714579081291059
