Assertion error on import of CVAT 1.1 annotation file with tracks

[mikhail-treskin]

My actions before raising this issue

• [x] Read/searched the docs
• [x] Searched past issues

Steps to Reproduce (for bugs)

1. Upload valid annotations file in CVAT 1.1 format (since annotation files on which the issue reproducible is a part of internal datasets, please contact me by email in profile to share them for reproducing). Tracks has no duplicated entries and all shapes are sequential by frame id
2. Wait for "Error: Request failed with status code 500. "AssertionError\n".." message

Expected Behaviour

Annotations uploaded with no errors

Same issue here! Hope it gets resolved soon.

I was able to reproduce this error by uploading COCO formatted labels (no tracks) and running the openvino Person re-ID function on it. I get the error when trying to sync annotations to a repository.

We've hit that multiple times.
