Here is the code example

    const params: Partial<Stripe.InvoiceCreatePreviewParams> = isRecurring
      ? {
          subscription_details: {
            items: priceArray.map((price) => ({ price })),
          },
        }
      : { invoice_items: priceArray.map((price) => ({ price })) };

    const preview = await this.stripe.invoices.createPreview({
      customer: dbuser.paymentSystemId,
      ...params,
      preview_mode: isRecurring ? 'recurring' : 'next',
    });

and example of the preview invoice lines:

{
  data: [
    {
      id: 'il_tmp_175897LT0n97qDN21653d625',
      object: 'line_item',
      amount: 3300,
      amount_excluding_tax: 3300,
      currency: 'pln',
      description: 'Cargo',
      discount_amounts: [],
      discountable: true,
      discounts: [],
      invoice: 'in_1QWk5zLT0n97qDN2KRhFfxH1',
      invoice_item: 'ii_1QWk5zLT0n97qDN26FC4fLHJ',
      livemode: false,
      ...
    },
    {
      id: 'il_tmp_1b099fLT0n97qDN2db1a2a72',
      object: 'line_item',
      amount: 2500,

    {

    }
  ]
}

Thanks for the info, looking in to this

[cold cove]

So the question is "why does it populate the lines list with nonsense"?

[fleet tendon]

Can you send me the request ID of a time that you made this request and got this response? (req_123)

[cold cove]

the request id should be inside invoice preview response?

[fleet tendon]

Correct, otherwise you can look in your dashboard logs
https://docs.stripe.com/api/request_ids
https://dashboard.stripe.com/test/logs

[cold cove]

ok for example this one:
req_yWbvawsCNFh6il

it includes only one one-time price object, but resulting a weirdo list

[fleet tendon]

Ah it looks like that customer has a subscription with those prices on it already. Basically your call is saying to preview what happens if you added an invoice item to the customer and did nothing else. In this case, the invoice item would get appended to the subscription's next invoice when it cycles. So here we need to add params to tell the endpoint to create an invoice for just the items that you specified. Figuring out how to do that

Having trouble figuring this out, will ask my colleagues and get back to you

[cold cove]

Thanks

Unfortunately we haven't been able to find a parameter for this for customers with subscription. I think the best workaround at the moment would be to provide customer details that match their billing address or whatever else is relevant here. That should preview an invoice for a theoretical new customer without anything else on them. I can put in a feature request to make this easier but I think that workaround is needed at the moment.
