Django serializers.save() does not use postgres - python-3.x

Question

I have the following function that runs automatically with cronjob, it makes predictions based on an anomaly detection model and it saves the results to a postgres database:
def prediction_job():
"""
This job will run once every batch_minutes minutes to predict if the IPs appear in these batch_minutes minutes are normal or malicious
and save the results to postgres
"""
ip_estimator = IpStatePrediction()
predictions = ip_estimator.predict_ip_state()
predictions_dict_final = convert_dict_for_serializer(predictions)
serializer_result = PredictionsSerializer(data=predictions_dict_final)
if serializer_result.is_valid():
serializer_result.save()
else:
logger.debug("Error with data {}.".format(serializer_result.errors))
When I run it locally after running the commands python3 manage.py runserver and python3 migrate --database postgres, it saves the results to postgres.
However on production I am getting the following error, when the function is executed:
Traceback (most recent call last):
File "/usr/local/lib/python3.8/site-packages/django/db/backends/utils.py", line 84, in _execute

return Database.Cursor.execute(self, query, params)

The above exception was the direct cause of the following exception:
