• [ x] Searched past issues

If you will create task with REST API, and in task labels definitions you will add attribute of input type checkbox, you will not be able to set attribute value in UI.

here is a minimal reproduction.
https://gist.github.com/codeistpl/190b3866871405192975c9f81ee4eca3

Environment

cvat setup with docker-compose
Docker version 20.10.5, build 55c4c88
docker-compose version 1.28.2
Server version: 1.2
Core version: 3.10.0
Canvas version: 2.2.1
UI version: 1.13.3

hash from develop branch:
eb1cb83

Steps to Reproduce

Reproduction steps:

1. setup cvat as in official guideline (run on localhost)
2. add user and password to match script with bug reproduction.
3. get reproduction script from https://gist.github.com/codeistpl/190b3866871405192975c9f81ee4eca3
4. put some image.png into same folder script.
5. run script, it will create task in cvat
6. login to cvat
7. open created task
8. open annotation job
9. make single annotation
10. try to modify annotation attributes
11. You will get - Could not update annotations Error: Trying to save an attribute attribute with id 150 and invalid value default_value

Workaround:

1. open task
2. click on label editor "RAW" mode (do not edit anything)
3. click on Done
4. now you can set attributes value.

Hi, I've successfully used checkboxes in the rest API in my project. But I create them like this:

{'name': 'My checkbox',
 'input_type': 'checkbox',
 'mutable': True,
 'default_value': 'false',
 'values': ['false', 'true']}

I'm on this commit e0fc323a4d649c34bcfee47f67b7efd9a54683a8
