[Python] Getting form results using python request

Admittedly, this is my first time using requests. The form I'm attempting to use is here: https://trade.cbp.dhs.gov/ace/liquidation/LBNotice/

Here is my code:

import requests

headers = {
'Accept': 'application/json, text/javascript, */*; q=0.01',
'Content-Type': 'application/json; charset=UTF-8',
'User-Agent': 'Mozilla/5.0',
'X-Requested-With': 'XMLHttpRequest'
}


payload = {
"dtPageVars":
{
"draw":1,
"columns":
[
{"data":"postedDate","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"eventDate","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"voidedDate","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"event","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"basis","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"action","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"entryNumber","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"portOfEntry","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"entryDate","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"entryType","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}},
{"data":"teamNumber","name":"","searchable":"true","orderable":"false","search":{"value":"","regex":"false"}}
],
"order":[],
"start":0,
"length":100,
"search":
{
"value":"",
"regex":"false"
}
},
"searchFields":
{
"portOfEntry":"0101",
"entryType":"01"
}
}

url = 'https://trade.cbp.dhs.gov/ace/liquidation/LBNotice/'
searchUrl = 'https://trade.cbp.dhs.gov/ace/liquidation/LBNotice/search'

response = requests.post(searchUrl, headers=headers, data=payload)

print(response.status_code)


I keep getting 500 status code but I am not sure why. Could it be the headers I'm using? I've tried many different combinations of headers without luck. Is it possible to use requests for this form or am I better off finding a different approach?

Any help would truly be appreciated. Thank you.
