Current Behaviour

I have MOT annotations saved in .zip format with the following structure

$unzip -l tracking_results.zip 
Archive:  tracking_results.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
    24059  2022-08-13 13:01   gt.txt
        3  2022-08-13 13:01   labels.txt
---------                     -------
    24062                     2 files

Here are the first few lines of the gt.txt file

0,0,0.7899999618530273,304.20000553131104,98.29000234603882,95.31000256538391,1,1,1.0

and the labels.txt file is simply

ok

However, when I try to upload these annotations using Upload annotations -> MOT 1.1 (on cvat.org I get an error saying

Error: Request failed with status code 500. "datumaro.components.errors.DatasetNotFoundError: Failed to find dataset at '/tmp/tmpcntvb5ty'\n".

What am I doing wrong? I think the format follows the one listed in the documentation.
