Theme

Expected behavior

Using shopify theme dev I want to access routes like /tools/recurring/get_rc_token/xxxxx (ReCharge app) or /account/logout.

Actual behavior

These routes fail and return 40X error codes when using shopify theme dev.

But they work in preview and in production.

It starts to fail after upgrading to Theme CLI 3.72 from an old version (I don't remember the version number).

Verbose output

$ shopify theme dev --store=reglopetfood --path dist
