yaml.representer.RepresenterError: ('cannot represent an object', Decimal('100'))

Describe the bug
When running the spectacular command to generate a schema in version 0.13.2 I get the following error:

yaml.representer.RepresenterError: ('cannot represent an object', Decimal('100'))

To Reproduce
Add the following field to any serializer.

    value = serializers.DecimalField(
        decimal_places=2,
        min_value=Decimal(1),
        max_value=Decimal(100),
        max_digits=5
    )

The problem is using Decimal for min_value and max_value. Changing those to just integers (1 and 100) solves the issue, but I think using Decimals should be supported too.

Expected behavior
The schema should be generated successfully.

Btw, this fixed my issue.
