msms-InvoiceLineItemDeletion

[keen onyx]

Is that Invoice Line Item attached to an Invoice? Billed already? Then you can't delete it. API Reference also mentioned

Deleting invoice items is only possible when they’re not attached to invoices, or if it’s attached to a draft invoice.

The invoice item is attached to a draft invoice of a subscription

Then yes it should be deletable

It tells me { type: 'StripeInvalidRequestError', raw: { message: "Can't delete an invoice line item that was generated by a subscription", type: 'invalid_request_error' } }
