"store/regions" endpoint returns: Unexpected token '<', "<!DOCTYPE "... is not valid JSON

[volfcan]

I've setup the backend and running, specify the .env files accordingly and trying to start the storefront and came across with this error. Any idea on how to fix that?

Error [SyntaxError]: Unexpected token '<', "<!DOCTYPE "... is not valid JSON

}

I think this is originated from this line

const { regions } = await fetch(${BACKEND_URL}/store/regions, {

in the middleware.ts file

Hello, i solve this by using the correct backend url in .env. i used the admin url (http://localhost:7001).

NEXT_PUBLIC_MEDUSA_BACKEND_URL=http://localhost:9000
