Hi Nikhilesh, A couple of things I notice right away: - The line starting `${headers}= Create Dictionary ` is missing the `Content-Type:` header - The line starting `&{multipart_file}= Create Dictionary`, `${CONTENT_TYPE}` should be the file’s content type (e.g. `text/plain`) not the `multipart/form-data` content type > where `'content-type'` is a string defining the content type of the given file Hopefully that’s all you need 🤞 Dave. ---

Hi Nikhilesh, I think you need to change this line: ```python ${file_content}= Get File ${FILE_PATH} ``` with this: ```python ${file_content}= Get File For Streaming Upload ${FILE_PATH} ``` Also FYI watch your variable names `${file_content}` is not the same as `${FILE_CONTENT}` Dave. ---

I change as per your suggestion but the error is same 2024-09-01 04:20:36.723 15a2bd3e-0f15-42d9-8a74-98023c25c550 ERROR - org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request ![image](https://europe1.discourse-cdn.com/flex005/uploads/robotframework1/original/2X/e/ee0ee3b48d984df39cb3296c4a25018244e1a63e.png) ---

Hi Nikhilesh, I wasn’t sure where to guide you from here, but after thinking on it a bit, I would try running the curl command with a -v switch and saving the request headers and request body from that command and compare it to what you have from requests library Look at the content-length header and make sure they are the same size when uploading the same file Then check the other headers and see if any are missing or extra.

Hi Nikhilesh, I also noticed these line breaks: ![image](https://europe1.discourse-cdn.com/flex005/uploads/robotframework1/original/2X/c/c461e7a15eaae9ab8873307cb69537e07f7fcf49.png) They looked a little odd to me, which made me look close and notice the & on &{multipart\_files} on the `POST On Session` line, I think on that line it should be a $ not &, so you could try that too. Dave. ---

Hi Nikhilesh, At least that error is telling you what’s wrong: This tuple is a 3-tuple not a 2-tuple ```python (“bulkinsert.txt”, open(“${FILE_PATH}”, “rb”), “${CONTENT_TYPE}”) ``` try changing it to: ```python (“bulkinsert.txt”, open(“${FILE_PATH}”, “rb”)) ``` I know the documentation said it supports 3-tuple and 4-tuples, but perhaps you found a bug in bulk\_upload or the documentation? Dave. ---

I am able to fix the issue. I use this File Valid ${headers}= Create Dictionary Authorization=Bearer ${ACCESS\_TOKEN} accept=application/json Create Session bulk\_upload ${BASE\_URL} verify=False ${file\_content}= Get File ${FILE\_PATH} ${file\_tuple}= Create List bulkinsert.txt ${file\_content} ${CONTENT\_TYPE} ${file}= Create Dictionary file=${file\_tuple} ${response}= POST On Session bulk\_upload ${ENDPOINT\_BULK\_UPLOAD} headers=${headers} files=${file} Should Be Equal As Numbers ${response.status\_code} 200 Thank you for your kind support 🙂
