In which of these areas are you experiencing a problem?

Theme

Expected behavior

It should run development server with the theme.

Actual behavior

Store: pro-lash-x-bella-lash.myshopify.com
Shopify CLI version: <output of “shopify version”>
Dev theme ID: 160635519220
Live theme ID: 160181420276
COmmand:

shopify theme dev --store pro-lash-x-bella-lash.myshopify.com --theme 160635519220
Error:
Theme ID mismatch: expected 160635519220 but got 160181420276.
Request ID: e78380d3-5509-4895-848b-9a27385d100e-1775801248

No shopify.theme.toml in the project.
env | grep SHOPIFY_FLAG prints nothing (no env vars).

Theme list:

Development (ac848f-tricore32-desktop) [development] [current] #160635519220
Tricore_ProLash_Essentials_PDLine | 3.5.0 [live] #160181420276

That Request ID allows Shopify engineering to inspect the failing upstream call and see why the live theme ID is being returned.

Reproduction steps

Just need to run the shopify theme dev command.
