Good you noticed that @mdelgado. I was only testing with online products. It seems to be that you cannot view old products. Although the scene ID is still in the database the XML data is also erased.
According to their documentation, there is a process to restore the data using the API but I will have to experiment with this. It seems to take some time to restore the data. For now I will add a check that will warn the user if the product is offline.
For now, i recommend to use online products. In most cases, it should be okay since the alignment of the Sentinel scenes is very good
