.shopifyignore changed after theme CLI 2.14.0?

Hi developers!

I run shopify theme serve at the root, and the .shopifyignore used to work in 2.13.0 I simply use it to ignore the scss folder to fit the project structure

The same way doesn’t seem to work in/ after 2.14.0 and I get the following error.

Currently, I just roll back to 2.13.0 to work on the themes.

Would you please help me take a look? Thanks!
