I need to set up my first Shopify App, in order to create a simple Express.js API who can make GraphQL request to modify a custom metafield value from storefront. I'm stuck at the beginning : set up my app dev environment. Because this is a really simple app project, I've used this Shopify-app-template-node and for now I'm just trying to run npm run dev and going to the app preview page. When I do this, nothing happens on my web browser, but console show many Error forwarding web request: AggregateError errors messages. I would expect to see the application's basic home page instead of this strange error. How can this problem be solved? Some additional information: My web/index.js and web/shopify.js files are currently identical to the repo version I need to expose three endpoints, but for now I just want to correctly run the basic version of the app The error Error forwarding web request: AggregateError only appears if I visit the preview page I tried npm install in the ./, ./web and ./web/frontend directories, and my shopify CLI is in LATEST (@shopify/cli/3.67.1) Here is the complete log, just after launching npm run dev command : > mj-wishlist-app@1.0.0 dev > shopify app dev ╭─ info ─────────────────────────────────────────────────────────────────────────────────────────────╮ │ │ │ Using shopify.app.toml for default values: │ │ │ │ • Org: dev │ │ • App: mj-wishlist-app [local] │ │ • Dev store: xxxx.myshopify.com │ │ • Update URLs: Yes │ │ │ │ You can pass `--reset` to your command to reset your app configuration. │ │ │ ╰────────────────────────────────────────────────────────────────────────────────────────────────────╯ 15:12:49 │ graphiql │ GraphiQL server started on port 3457 15:12:50 │ web-backend │ 15:12:50 │ web-backend │ > shopify-app-template-node@1.0.0 dev 15:12:50 │ web-backend │ > cross-env NODE_ENV=development nodemon index.js --ignore ./frontend 15:12:50 │ web-backend │ 15:12:50 │ web-frontend │ 15:12:50 │ web-frontend │ > shopify-frontend-template-react@1.0.0 dev 15:12:50 │ web-frontend │ > vite 15:12:50 │ web-frontend │ 15:12:51 │ web-frontend │ 15:12:51 │ web-frontend │ VITE v5.4.7 ready in 414 ms 15:12:51 │ web-frontend │ 15:12:51 │ web-frontend │ ➜ Local: http://localhost:49717/ 15:12:51 │ web-backend │ [nodemon] 2.0.22 15:12:51 │ web-backend │ [nodemon] to restart at any time, enter `rs` 15:12:51 │ web-backend │ [nodemon] watching path(s): *.* 15:12:51 │ web-backend │ [nodemon] watching extensions: js,mjs,json 15:12:51 │ web-backend │ [nodemon] starting `node index.js` 15:12:52 │ web-backend │ [shopify-api/INFO] version 11.4.0, environment Node v20.15.1 15:12:52 │ web-backend │ [shopify-api/INFO] Future flag lineItemBilling is disabled. 15:12:52 │ web-backend │ 15:12:52 │ web-backend │ Enable this flag to use the new billing API, that supports multiple line items per plan. 15:12:52 │ web-backend │ 15:12:52 │ web-backend │ [shopify-api/INFO] Future flag customerAddressDefaultFix is disabled. 15:12:52 │ web-backend │ 15:12:52 │ web-backend │ Enable this flag to change the CustomerAddress classes to expose a 'is_default' property instead of 'default' when fetching data. 15:12:52 │ web-backend │ 15:12:52 │ web-backend │ [shopify-api/INFO] Future flag unstable_managedPricingSupport is disabled. 15:12:52 │ web-backend │ 15:12:52 │ web-backend │ Enable this flag to support managed pricing, so apps can check for payments without needing a billing config.
