Update of json field failed

[zahraj3]

I have defined field "parameters" where is store json.

Displaying of the values is fine and working. But the update of json values cause this error:

It is not important if the filed is the set as text or json (I mean setting in the motor-admin yml)

I would really appreciate it if it could be fixed.

Thanks a lot.

@zahraj3 do you have some custom AR serializer for your json field? Default AR jsonb fields work with motor admin without additional configurations.
