FILE_NOT_SUPPORTED Error making Bulk Write request

FILE_NOT_SUPPORTED Error making Bulk Write request

Hello, I am trying to perform a Bulk Write request to the Leads module of Zoho CRM. I am able to successfully upload a zipped CSV file but I get the following error when I initiate the bulk write job:
  1. 400 - {"status":"error","code":"FILE_NOT_SUPPORTED","message":"File not supported for bulk write","details":{}}


Here is the CSV data:
  2. Email,First_Name,Last_Name
  3. admin@mydomain.com,john,doe
And here is the request I am using to upload the zipped CSV

  2. curl "https://content.zohoapis.com/crm/v5/upload" \
  3. -X POST \
  4. -H "Authorization: Zoho-oauthtoken 1000.xxx.xxx" \
  5. -H "X-CRM-ORG: 64990321" \
  6. -H "feature: bulk-write" \
  7. -F "file=@leads.zip"

I received a file ID from this upload request and make this bulk write request

  2. curl "https://www.zohoapis.com/crm/bulk/v5/write" 
  3. -X POST 
  4. -H "Authorization: Zoho-oauthtoken 1000.my-token.xxx" 
  5. -H "Content-Type: application/json" 
  6. -d "@app/services/zoho/payload.json"
And here is the payload.json
  2. {
  3.   "character_encoding": "UTF-8",
  4.   "operation": "insert",
  5.   "ignore_empty": true,
  6.   "resource": [
  7.     {
  8.       "type": "data",
  9.       "module": { "api_name": "Leads" },
  10.       "file_id": "1767869000159543001"
  11.     }
  12.   ]
  13. }

Can you please tell me why I get the error "File not supported for bulk write"

I know that uploaded files cannot be reused multiple times, this error happens the first time I attempt to import an uploaded file.
