pymupdf.mupdf.FzErrorGeneric: code=1: Director error: <class 'AttributeError'>: 'JM_new_bbox_device_Device' object has no attribute 'layer_name'

Description of the bug

Description of the bug
Calling get_bboxlog(layers=True) raises an exception related to missing layer_name attribute on the internal device object.

How to reproduce the bug

How to reproduce the bug
Using a valid PDF file, run the following code:

def extact_graphics(filepath: str):
    doc = pymupdf.open(filepath)
    graphics_page = list(doc)[-1]
    drawings = graphics_page.get_bboxlog(layers=True)


fn = 'path/to/error/pdf'
extract_graphics(fn)

Expected behavior
get_bboxlog(layers=True) should return a list of drawing instructions with associated bounding boxes. Instead, it crashes with an internal C++/Python callback error:
