PayPal payment session not being updated after cart is updated

[Arsenalist]

Node: 18
Medusa 1.20.9,
PayPal plugin: 6.0.4
OS: MacOS

Steps to reproduce:

• Add 1 item to cart for $10
• Create PayPal payment session, it will be for $10
• Click PayPal button to see popup prompt to pay for $10
• Close popup
• Change quantity of item in cart to 2, so total is $20
• Click PayPal button again, it will still say $10 when it should say $20

The call to PayPal API is happening OK in PayPalProvider.updatePayment() but the PayPal order ID does not reflect the new value.

In PayPal console, the PATCH request which is supposed to update the amount to $20 has no data associated with it:

This makes sense as it's calling patch order in the paypal-sdk file and that doesn't send any data (even though data is passed into it):

  async patchOrder(orderId: string, data?: PatchOrder[]): Promise<void> {
    const url = PaypalApiPath.PATCH_ORDER.replace("{id}", orderId)
    return await this.httpClient_.request({ url, method: "PATCH" })
  }

Perhaps the fix is to actually pass the data into the call?

Hi @srindom @carlos-r-l-rodrigues , having a similar bug, but instead of editing the quantity for the item I get it after adding another item or a shipping method

looking into the code I think this update wasn't published

@olivermrbl #8455 is missing a changeset and wasn't included in the release.

Thanks @ximenadev for the heads up

Nice catch, will publish a new release later today.

Correction: We haven't published these changes yet. Will do that today.
