Unable to set up Web Pixel App Extension

[keenborder]

Hello everyone, I hope everyone is doing well. I am trying to build a simple Shopify app that uses the Web Pixel extension. In order to integrate the extension, I have followed the official tutorial on the Shopify website: https://shopify.dev/docs/apps/marketing/pixels/getting-started. However, I am encountering an issue in step 5. When I try to run the GraphQL code in step 5, I receive the following error:

Other people have also been experiencing the same error:
https://community.shopify.com/c/extensions/how-to-create-the-web-pixel-using-the-admin-api-grapql/m-...
https://github.com/pulkitgangwar/shopify-web-pixel-api-example/issues/1
The response says, "No extension found," but the extension has already been created using the "generate extension" command and gets installed when running the app using "dev." I feel like this might be a bug with the Shopify GraphQL API itself.

For more context I am using express to create the endpoint for the Post request:

app.post("/api/protected/webpixel", async (_req, res) => {
  const client = new shopify.api.clients.Graphql({
    session: res.locals.shopify.session,
  });
  const response = await client.query({
    data: {
      query: `
      mutation webPixelCreate($webPixelInput: WebPixelInput!) {
        webPixelCreate(webPixel: $webPixelInput) {
          webPixel {
            settings
            id
          }
          userErrors {
            code
            field
            message
          }
        }
      }
      `,
      variables: {
        webPixelInput: {
          settings: {
            accountID: crypto.randomUUID(),
          },
        },
      },
    },
  });

  if (response.body.data.webPixelCreate.userErrors.length) {
    console.log(JSON.stringify(response, null, 4));
    const errors = queryResponse.body.data.webPixelCreate.userErrors;
    throw new Error(errors.map((error) => error.message).join(" , "));
  }

  return response.body.data.webPixelCreate.webPixel;
});

The request is sent by a simple button created in "react". I even tried using an external client with my store's access token generated from a private app with admin access, but the same error is returned. Please help me in this regard.

 settings: {

          },
