Hello ! I'am building a flask app that require shopify API call. yesterday my create_shopify_checkout function was able to return a checkout cart. Today, the checkout web_url returned is empty. it looks like it can fetch the correct variant_id since the image_url provide the expected image for that variant.
I may have made modification to the dev store and/or the app at shopify pages, but I can't figure out which one is responsible for that problem.
Also, yesterday, when the cart checkout was not returned as empty, I was able to click on the checkout link. Now if I click on the checkout link, it require a password.
here is my python code for the create_shopify_checkout.
