InputObjectType causing encoding issues with JSONField

[adilhussain540]

Note: for support questions, please use stackoverflow. This repository's issues are reserved for feature requests and bug reports.

• What is the current behavior? I have an InputObjectType with multiple fields and receive it in my mutation as a param. But it throws Object of type proxy is not JSON serializable on passing it as a JSONField parameter for object creation.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via a github repo, https://repl.it or similar. I have the following Django model with a JSONField inside:

  
  from django_jsonfield_backport import models as mysql

class RaceReport(TimeStampedModel): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='race_reports') parameters = mysql.JSONField(blank=True, default=dict)

Then, there's a custom `InputObjectType` which looks like this:

class ParametersInput(graphene.InputObjectType): start_point = BigInteger(required=True) end_point = BigInteger(required=True) data_type = DataType()

I am using the above input type inside the following `Mutation`:

class CreateRaceReport(graphene.Mutation): class Arguments: parameters = ParametersInput(required=True)

def mutate(_root, info, parameters):  # noqa: N805
    race_report = RaceReport.objects.create(user=info.context.user, parameters=parameters) # origin of the error
    return CreateRaceReport(race_report=race_report)

* **What is the expected behavior?**
The `InputObjectType` should be resolved after we access its attributes or use`parameters.__dict__` but it stays lazy and causes the JSON encoding errors.

* **What is the motivation / use case for changing the behavior?**
Better compatibility with `JSONField`.
