Hi @Shinyzack123! Thank you for your patience as we look into this. Based on the inputs we got from the relevant teams, we suggest that you try running your code again, but this time, please set a value to the parameter client_order_id (unique uuid for this order) instead of default. In addition, please note that we also found a forum post that could be helpful with your case scenario. We highly suggest that you try looking into this for reference, since the user provided a random client_order_id generator which you could also embed in your code.
Please do not hesitate to reply back to this thread if you still have queries/concerns. Thank you and have a great day!
