Empty annotation list when exporting dataset to COCO Keypoints 1.0 format

[hayawar]

I have a annotated a dataset with 4 key-points using CVAT online. When I exported it in COCO Keypoints 1.0 format, the annotation details were missing from the exported json file. However, when changing the export format to CVAT for images 1.1 or Datumaro 1.0, the keypoints get successfully exported.
I still need the annotation exported in coco format. So i'm trying to figure out what went wrong or if I misunderstood something in coco annotation. I'd appreciate any help.

The empty annotation list in exported json:

the four labels

Hi, @haya-alwarthan

This format can only export skeleton annotations. Do you have skeleton annotations?
I see that among the categories you only have labels, for this task you need skeletons.
If you want to know more about skeletons, you can watch this video.

Thank you! I have just tried skeleton annotation and it worked. Any idea if there was a possibility to convert my current labels to skeleton without redoing it all over ?

There is no ability to convert labels in this way.
The only option I can suggest is to dump your annotation in another format, convert it manually to keypoints format with a script and upload to a task/project where skeletons are already configured.
