const client = new Client(YOUR_LEXOFFICE_API_KEY);All functions are promise based. These promises are formatted by the ts-results package, for extended error handling see Error handling.

}As mentioned above, the returned promises are formatted by ts-results which is a typescript implementation of Rust's Result and Option objects. It brings compile-time error checking and optional values to typescript. All errors are instances of type RequestError. If you want to use the advantages of ts-results, all client responses should be processed similar to the following:
if (YOUR_RESULT.ok) {
const YOUR_VARIABLE = YOUR_RESULT.val;
// Work with your result
} else {
// Your request returned an error
const error = YOUR_RESULT.val;
console.log('error:', error);
// Further error checking is possible by
if (error instanceof RequestError) {
console.log('Hello instance of RequestError!');
if (error instanceof RequestNotFoundError) {
console.log('Wow, it looks like you have many instances!');
}
if (error instanceof RequestMethodNotAcceptableLegacyError) {
console.log('Seems, that you take care of your legacy!');
}
}

Only possible for any type of vouchers that are not in "draft" mode.
The required id is not the id itself, it is the documentFileId, which can be required with the matching method and the vouchers id:
renderCreditNoteDocumentFileId(id);
renderInvoiceDocumentFileId(id);
renderOrderConfirmationDocumentFileId(id);
renderQuotationDocumentFileId(id);
