I get ERROR: REJECTED when uploading a file to ShareFile

Question

I am trying to upload a file to ShareFile. In Postman, I am able to do it but in Python get 200 status code and "ERROR: REJECTED" response body.

Here's my code.

def upload_file(self, file: bytes, folder_id: str, file_name: str, etag: str, content_type: str):
        url = f"{self.api_base_url}/sf/v3/Items({folder_id})/Upload2"
        headers = self._get_headers()

        # First, get URL for file upload
        response = requests.post(url, headers=headers, json={
            "FileName": file_name,
            "Raw": True,
        })
        upload_url = response.json().get("ChunkUri")

        headers = self._get_headers()
        headers["Content-Type"] = content_type
        response = requests.post(upload_url, headers=headers, data=file)

Answer 1

When getting the URL, FileSize also has to be specified unless it's specified elsewhere.

# First, get URL for file upload
response = requests.post(url, headers=headers, json={
    "FileName": file_name,
    "Raw": True,
    "FileSize": len(file),
})
