Create a Quick Expense with an Image with '500 Error'

[hjtso]

It could be used curl to Create a Quick Expense with an Image(create-quick-expense-image) , but when it was executed with python, there was a "500 - Internal Server Error" problem.
I also tried to save file 'Image_1.jpg' as a Base64 encoded image, it was also "500 - Internal Server Error".
Is there any thing wrong with the format or endpoint?

● curl command：OK

curl -X POST \
https://us.api.concursolutions.com/quickexpense/v4/users/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/context/TRAVELER/quickexpenses/image \
  -H 'Authorization: Bearer {access_token}' \
  -H 'Content-Type: multipart/form-data' \
  -H 'concur-correlationid: quick-expense-with-image' \
  -H 'content-type: multipart/form-data' \
  -F fileContent=@/Users/Downloads/Image_1.jpg \
  -F 'quickExpenseRequest={
  "expenseTypeId": "JPYPTRAN",
  "transactionAmount": {
    "currencyCode": "USD",
    "value": 99.05
  },
  "transactionDate": "2020-02-02"
}'

response result：
{"quickExpenseIdUri":"https://seapr1qes.concurasp.com/quickexpense/v4/users/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/context/TRAVELER/quickexpenses/33585510B733F3429F975D4E81B1AFFC"}
