Theme

Expected behavior

the command shopify theme dev should start the development theme

Actual behavior

When I use shopify theme dev the CLI fails with the error message:

Failed to fetch theme:
No additional information or suggestions are provided, making it difficult for the user to understand the root cause or how to resolve the issue. The theme also does not exist, when I try to use shopify theme delete.

A member of our team encountered this issue earlier today. They were using the latest version of the CLI and Node v21.0.0.

We weren't able to determine a root cause, but logging out and back in solved the issue.
