Unable to add time to TimeField in django model [<class 'decimal.InvalidOperation'>] - django

Question

I have a django model like this...
class ConversionResults(models.Model):
conversion_results_id = models.AutoField(primary_key=True)
conversion_rate_a = models.DecimalField(max_digits=4, decimal_places=2)
clicks_a = models.IntegerField()
conversion_rate_b = models.DecimalField(max_digits=4, decimal_places=2)
clicks_b = models.IntegerField()
week = models.IntegerField()
date = models.DateField()
time = models.TimeField()
objects = models.Manager()
class Meta:
db_table = 'conversion_results'
def __int__(self):
return self. conversion_results_id
When I try to add data to the model, like below
ConversionResults(
conversion_rate_a=conversion_rate_today_a,
conversion_rate_b=conversion_rate_today_b,
clicks_a=ctc_today_a,
clicks_b=ctc_today_b,
week=week,
date=today_date,
time=datetime.datetime.today().time() # the error is here
).save()
I am getting error with the time field as shown below
graphql.error.located_error.GraphQLLocatedError: [<class 'decimal.InvalidOperation'>]
I don't get how this is even related to decimal, the model contains a TimeField. Any help will be appreciated
