The definition of the field (found here ) says that the field should be an `unsigned long`. IDL defines an unsigned long as 32-but unsigned integer (found here ).

The `PixelPin - Picture Login` entry with AAID `0056#0002` has a minComplexity of 34359738368 which does not fit in an unsigned int, causing parsing issues when trying to unmarshal the metadata blob.

Either the documentation should be amended to indicate that this field can be an unsigned long long, or this invalid data should be amended.

interesting, no idea how their thing works, their website now redirects to some AI stuff. I think no one expected the minimum complexity to be THIS high.
