`/openslides_backend/models/fields.py` line 196 raises a `NotImplementedError`

[GabrielInTheWorld]

I sent this payload:

{
    "action": "user.update",
    "data": [
        {
            "id": 4,
            "pronoun": "",
            "title": "",
            "first_name": "ash",
            "last_name": "",
            "username": "ash",
            "is_active": true,
            "is_physical_person": true,
            "default_password": "ash",
            "email": "",
            "default_vote_weight": null,
            "number_$": {},
            "structure_level_$": {},
            "vote_weight_$": {
                "2": null
            },
            "about_me_$": {
                "2": ""
            },
            "comment_$": {
                "2": ""
            },
            "vote_delegated_$_to_id": {},
            "vote_delegations_$_from_ids": {
                "2": []
            },
            "group_$_ids": {
                "2": [
                    8
                ]
            }
        }
    ]
}

and got this error:

Maybe this is related to #1228.

I cannot replicate your error. Can you try again with https://github.com/OpenSlides/openslides-backend/pull/1243 and post the occuring error? I added some more context to the thrown exceptions.

[r-peschke]

Look at the default_vote_weight: It is a defined as a decimal-field with the default-value of 1 and a minimum of 0. In your payload you try to st it null. This comparison with the minimum value raises the exception.

[jsangmeister]

Ah thank you! I was confused by the code snippet from @GabrielInTheWorld in the other issue, which was another place ;) But in this case, this is easy to fix.
