Empty certificate serial when I retrieve a transaction

[ghost]

Here is the JSON object that is returned :
{"number":225,"time_start":1574262044,"time_end":1574262045,"certificate_serial":"","type":"ORDER","state":"ACTIVE","client_id":"19314bd6-307c-378b-96d2-822574db1da1","data":{"aeao":{"receipt_type":"ORDER","line_items":[{"quantity":"1","text":"Coca","price_per_unit":"2.20"},{"quantity":"1","text":"Fanta","price_per_unit":"2.20"},{"quantity":"2","text":"Cesar salad","price_per_unit":"8.50"},{"quantity":"1","text":"Filet mignon","price_per_unit":"20.00"},{"quantity":"1","text":"Margherita pizza","price_per_unit":"15.00"}],"amounts_per_vat_rate":[{"vat_rate":"5.00","amount":"4.40"},{"vat_rate":"19.00","amount":"52.00"}],"amounts_per_payment_type":[{"payment_type":"CASH","amount":"56.40"}]}},"revision":1,"latest_revision":2,"log":{"operation":"StartTransaction","timestamp":1574262044},"signature":{"value":"AFqqBicgEupIQAeft5zwlgIt45mJjjkFMC507xGd63iuqIMB2C1oS7h/3mqF62KKZBJJoJWU8mLwwZQ0I7JHYw==","counter":441},"tss_id":"19314bd6-307c-378b-96d2-822574db1da1","metadata":{},"_type":"TRANSACTION","_id":"5d0d64dd-846f-34a4-b3d2-a04ccbf1014c"}

As you can see the "certificate_serial" is empty.
However, this problem only occurs when I try to retrieve a transaction (https://kassensichv.io/api/docs/#operation/retrieveTransaction), NOT when I create one.

Thanks for the heads-up.

We located the issue in our backend and applied a fix. I will inform you as soon as it is patched on the live system.

Great job. Thank you.

@Greelings Just as a side-note. The same behavior appears to be in ListTransactions and ListAllTransactions. We are aware of this and fixed this in the same fix as mentioned above.

Ok, perfect.

Bugfix is now on the live system. Thanks again for the report.
