According to BILD, a chain of mistakes by maintenance AND pilots leads to the near crash landing. It has a paywall, so I translated some parts.

According to BILD information, sloppiness is supposed to be the main cause. In concrete terms: Lufthansa's technicians as well as the air force pilots did not carry out all the required checks. Officially, the investigations are still being carried out by the "General Flugsicherheit" of the Bundeswehr.

Meanwhile Lufthansa circles say that a chain of mistakes and carelessness led to the near crash. Error 1: Incorrect wiring of the spoilers on the wings. So much was known. Reason: Maintenance breakdowns at the responsible maintenance company "Lufthansa Bombardier Aviation Services". Error 2: Missing checks! After completion of maintenance, the technicians must actually release the aircraft on the basis of a checklist. Lufthansa Technik confirmed this to BILD: "Regardless of the specific case, a maintenance and overhaul company releases an aircraft from service after maintenance or overhaul work has been carried out". However, the government aircraft obviously did not receive such a carefully performed check to declare "airworthiness". Error 3: Obvious negligence on the part of the pilots. Because they also have to carry out routine checks before take-off, during which the wrong wiring of the spoilers should have been noticed on the ground. And even in the air there would be possibilities to switch off the wrongly wired spoilers. That was omitted.
