Getting an 400 Bad Request error while sending post request with formdata

Hi Team ,

So I am using robot framework request library to send POST request with form-data body type which has two key parameters date and file so while sending this data I am getting an error of POST Response : url= status=400,
reason=Bad Request headers={‘Date’: ‘Thu, 30 Mar 2023 07:59:28 GMT’, ‘Content-Type’: ‘application/json’, ‘Content-Length’: ‘48’,
‘Connection’: ‘keep-alive’, ‘server’: ‘uvicorn’} body={“detail”:“There was an error parsing the

I have created a below script :
Create Session myssion
${headers}= Create Dictionary Content-Type=multipart/form-data
${reporting_date}= Set Variable 20230303
${prev_result_file}= GET FILE FOR STREAMING UPLOAD api_test/test_data/eod_valuation_20230302.xlsx
${files}= Create Dictionary file ${prev_result_file}
${data}= Create Dictionary reporting_date=${reporting_date} prev_result_file=${files}
${resp}= Post On Session myssion /test-upload/ headers=${headers} data=${data}

You’re sending a body that is a dict with two keys (reporting_date and prev_result_file of which the later is a dict with a single key file). Are you sure that is the expected body structure?
