Not able to persist cart update

[kvedantmahajan]

Here's my code for _saveCart

_saveCart() { this._onItemsUpdated(); return fetch(${API_ENDPOINT}api/cart/items, { method: 'PUT', headers: { 'content-type': 'application/json' }, body: JSON.stringify({ data: this.items }) }).then(res => res.json()) .then(res => res.data) .catch(error => console.error(error)); }

PUT request is successful. However, as I refresh the page, data is gone.

Where should I look for to add missing pieces to work it around?

@kushalmahajan Can you push your code to github so I can take a look?

Here - https://github.com/kushalmahajan/pwa-fundamentals/tree/reporting-update-cart-bug

I checked terminal and there on refreshing the page there is this error -

Unhandled rejection TypeError: Cannot read property 'map' of undefined at

divideCartWork (/Users/vedant/Projects/pwa-fundamentals/server/api-server/routes/cart/update-items.js:15:25)

Nothing seems to work fine after this error. There is a failed fetch request for

GET https://localhost:3000/order/web-app-manifest.json 404 (Not Found)

Manifest: Line: 1, column: 1, Unexpected token.

And my service worker will not install after this :(

I'll have to take a look later. Make sure your PUT payload matches what you find I the API markdown file In the root of the project. The .map issue sounds like an array was expected and might be missing from your payload For world-class web developer training: https://mike.works

I know but I am doing that in modified functions. It sure came up in the video too but not sure where's it coming from now. Warm Regards, Kushal V. Mahajan
