Describe the bug
I am using aftership-sdk-python library (aftership==1.0.post2) api create tracking api for posting orders to aftership since a month ago. I am using it as a batch process, processing around 10k records per day. since 2 days back, for few records I am getting this error below.. I tested my code, the argument I pass has no error but I get this error in the python module

Traceback (most recent call last):
    aftership.tracking.create_tracking(tracking=track_dict)
  File "/opt/root/lib64/python3.8/site-packages/aftership/tracking.py", line 10, in create_tracking

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I get this error while using below code in loop

dict = {   "slug": carrier,
               "title": "",
               "emails": "",
               "customer_name": "",
                "order_id": order_id
           }

aftership.tracking.create_tracking(tracking=dict)

Could you please let me know how can I tackle this error, what happens sometimes is that even if I get this error, the record sometimes still gets posted to aftership, so if it tries to run second time I get BadRequest: Tracking already exists. as this outcome is related to another piece in my code, so I might need this error handled.

Please let me know if you need more details about this error.

Update:

If I add content-type in headers, will that solve my problem ? something like below: Please let me know

tracking = aftership.tracking.create_tracking(tracking=track_dict, headers={"Content-Type": "application/json"})

Thanks
