Not a JPEG file: starts with 0xff 0x11

[PixelbPioneer]

Hello! When I was running create_patches_fp.py and extract_features_fp.py, some of my svs files would prompt an error: openslide.lowlevel.OpenSlideError: Not a JPEG file: starts with 0xff 0x11. However, I was able to check the information of the svs files that caused the error using level_downsample = slide.level_downsamples[level].. The specific error message is as follows:

Traceback (most recent call last):

I wonder the reason for this error and how to deal it. Many thanks for the explanation.
