Context

I got this issue:

cvat.apps.dataset_manager.bindings.cvatimporterror: failed to import item ('obj_train_data/frame_3691', 'train'): malformed folder structure for image obj_train_data/frame_3691.jpg

I have followed the steps that can be solved the current issues as follows:

1. check the zip file sturcture and the structure was confirmed as suggested

yolo_dataset.zip/
├── obj.names
├── data.yaml
├── obj_train_data/
│ ├── frame_0000.jpg
│ ├── frame_0001.jpg
│ └── ...
├── obj_train_labels/
│ ├── frame_0000.txt
│ ├── frame_0001.txt
│ └── ...

2. validate the zip file and it was validated and unzipped sucessfully it to check the structure and files. the all files are not contagious
3. check the name of *.jpg" file is matched with .txt file which is annotation and every jpg files are exactly matched with their txt files
4. check the data.yaml fiel is correctly formatted and in the ZIP's root directory and it the file is as following:

train: obj_train_data/
val: obj_train_data/

names:
0: referee
1: our_team
2: opponent_team
3: our_goalkeeper
4: opponent_goalkeeper
5: sports ball

the issue file is frame_3691.jpg
I have tried many things to correct it, but I have no problem at all.
It is located the desginated folder and has the matched txt file as well.
I think the cvat has serious problem with uploading annotation.

Environment

Yes, I also encountered the same problem. When I use CVAT exported zip, I can directly import tags, but if I decompress and compress it again, the resulting compressed file cannot import tags.
I use the Windows system for decompression and compression operations, and I am not sure if it is because I am using the Windows system instead of the Linux system for compression.
