Error 503, Script tag cache with API version 2021-01

Technical Q&A

Hello,

I tried to use script tag cache with API version 2021-01.

This is my script:

const scriptTagBody = {
                        "event": "onload",
                        "src": `${HOST}/js/bss-b2b-cp.js`,
                        "cache": true
                    };

But it didn’t work. This is error message:

GET https://cdn.shopify.com/proxy/062ed39eab9b80108a81db70f4c5d95620f0e4daa285921d5829ee21abf460a6/dev-b2b-solution.bsscommerce.com/js/bss-b2b-cp.js?shop=dev-b2b-solution.myshopify.com&sp-cache-control=cHVibGljLCBtYXgtYWdlPTkwMA net::ERR_ABORTED 503

How can I make it work?
