No shop provided

[isferrei]

I'm developing an app on shopify, but when I make api calls after the line 

app.use("/api/*", shopify.validateAuthenticatedSession()); of index file, it gets the issue "No shop provided". I could see that shop is undefined in payload. When I put my api calls before this line it works. I'm sharing the file code below.

// @TS-check

import { join } from "path";

import { readFileSync } from "fs";

import express from "express";

import serveStatic from "serve-static";

import shopify from "./shopify.js";

import GDPRWebhookHandlers from "./gdpr.js";

import applyAttributesApiEndpoints from "./middleware/note-attributes-api.js";

const PORT = parseInt(process.env.BACKEND_PORT || process.env.PORT, 10);

const STATIC_PATH =

  process.env.NODE_ENV === "production"

    ? `${process.cwd()}/frontend/dist`

    : `${process.cwd()}/frontend/`;

const app = express();

// Set up Shopify authentication and webhook handling

app.get(shopify.config.auth.path, shopify.auth.begin());

app.get(

  shopify.config.auth.callbackPath,

  shopify.auth.callback(),

  shopify.redirectToShopifyOrAppRoot()

);

app.post(

  shopify.config.webhooks.path,

  shopify.processWebhooks({ webhookHandlers: GDPRWebhookHandlers })

);

// If you are adding routes outside of the /api path, remember to

// also add a proxy rule for them in web/frontend/vite.config.js

app.use("/api/*", shopify.validateAuthenticatedSession());

app.use(express.json());

applyAttributesApiEndpoints(app);

app.use(serveStatic(STATIC_PATH, { index: false }));

app.use("/*", shopify.ensureInstalledOnShop(), async (_req, res, _next) => {

  return res

    .status(200)

    .set("Content-Type", "text/html")

    .send(readFileSync(join(STATIC_PATH, "index.html")));

});

app.listen(PORT);

Just happened to me because I forgot the "/" at the beginning of my request url.

this line ----> app.use("/api/*", shopify.validateAuthenticatedSession());

ensures your requests get automatic validation (headers and shit, API_key and whatnots, idk)

so just make sure every one of your requests start with "/api/", with both dashes in front and after...

Hello. I have the same issue. I've used slash before every api url. Any other ideas to try ?
