Could not upload annotation for the task Error: Request failed with status code 500. "KeyError: 53\n".

I did very much similar to the below mentioned process and getting error while uploading the annotations back to task

1. I uploaded one picture from server, and created an annotation with shape "box". Then I saved the work, and dumped the annotation to my local drive.

2. I opened the dumped json file, and removed all values inside the "segmentation" within "annotation", and saved this file.

3. I uploaded the modified annotation to the same project, and then it gave an error, without any message, only a "ok" button.

4. Then I try to save the work, however, it does not allow me to save it, and gave the 500 error message like following:
   

5. Then I click the go back button from browser, and went back the the dashboard, and click "delete task", then it shows me the following error message:
   

The modifed coco file is attached for your convenience, I changed the format to txt so I can upload it here.
14_realdemo000000.txt

For the second question, we already generated some annotations with our own algorithm in COCO format, since we are not using any masks or polygon, we have only bbox, and no segmentation is needed for this project.

For the last one, the only thing I can think of now, is to remove the constraint on segmentation,
so when we don't need it, we can leave it blank.

Thank you.
