DELETE /store/carts/:cartId/line-items/:itemId throws error when it is the last item in cart | Medusa Community | Page 1

If you create payment session and then try to empty the cart you get an error:

 parameters: [ NaN, 'ps_01GY5Z7V44F2FQ4J0RGE6PERVJ' ],```

This is happening with 1.8.0 and Stripe Plugin 2.0. I had reported a similar issue which was fixed but this appears to be a new type of error. https://github.com/medusajs/medusa/issues/3333

I can't reproduce this issue. Looking at the github issue you linked, you write about an error from the Stripe logs. You seem to be making a request to Stripe that throws the error. Can you give the clear sequence of what queries you are making to what endpoints, and where exactly you get the error? Might this have something to do with the way you have implemented stripe on the frontend? I added some things to cart, selected a payment session, and then deleted all items from the cart one by one. I did not get any errors in the medusa console or the stripe logs.

Throws an error where? In the medusa console? Please post the error

#

Is it in the postgres log?

latent lagoon Throws an error where? In the medusa console? Please post the error

The error I posted in the original message. It’s a Postgres error where it’s trying to update the column with a NaN

Have you been able to reproduce the error with the default medusa nextjs starter? I get a large number of request errors when I look at the network tab of the console log, even before I attempt to checkout.

Those 400s you see in the request log is some polling stuff.

I looked at this more and on this line total is evaluated to NaN which results in this error. https://github.com/medusajs/medusa/blob/649bb6aa999a50c91d603dc18ccd6559b1819eb2/packages/medusa/src/services/cart.ts#L1843

This makes sense as on this line when total is calculated, no checks are done on whether what's being added isn't a NaN https://github.com/medusajs/medusa/blob/649bb6aa999a50c91d603dc18ccd6559b1819eb2/packages/medusa/src/services/cart.ts#L2641

In my case the values are as following:

discount_total: 0,
item_tax_total: 0,
shipping_total: 0,
shipping_tax_total: NaN,  <<<<<<<<
gift_card_total: 0,
gift_card_tax_total: 0,
tax_total: NaN,   <<<<<<<<```

#

And looking at it deeper, this is NaN because it iterates over the shipping methods to calculate the total and the Shipping Method has NaNs in there:

```

ShippingMethod {
id: 'sm_01GY8FEJ7HBQP7JC0WSH9WBJ67',
shipping_option_id: 'so_01GSB9B275NWPHV2VM3EXQVF0H',
order_id: null,
claim_order_id: null,
cart_id: 'cart_01GY5QQ40V15E49WRR45D8HJ75',
swap_id: null,
return_id: null,
price: 0,
data: [Object],
tax_lines: [Array],
shipping_option: [ShippingOption],
original_total: NaN,
total: NaN,
subtotal: 0,
original_tax_total: NaN,
tax_total: NaN
}

Any thoughts on why there are NaNs when I add a shipping method?
