Do you have any more details on that? I've only found mention of "during maintenance".
PS
From:

Boeing has ordered the inspection of all undelivered 737 Maxes, after it found debris in the wing fuel tanks of some of the grounded narrowbodies.
The airframer states that it has also recommended 737 Max customers globally with aircraft in active storage for more than a year to inspect the fuel tank for foreign object debris (FOD).
The company states it first discovered FOD while conducting maintenance on undelivered 737 Maxes in storage at its Renton facility.
That finding led to a robust internal investigation and immediate corrective actions in our production system. We are also inspecting all stored 737 Max airplanes at Boeing to ensure there is no FOD,” the airframer states.
That isn't giving me a warm feeling that the FOD was found by a regular check made on all planes as part of pre-delivery.
I would like to be reassured.
