Describe the problem/error/question
I am trying to upload a pdf documment to Salesforce using the ContentVersion API. I can get the API call to work in CURL and Postman but cannot seem to get it to work in n8n. My prior node successfully gets the PDF and uses the default field name “data”, I can view and download the file. I have tried using the HTTP Request node to peform the same call without luck both importing the CURL and creating from scratch. I’ve tried a couple variations where you send all the non-binary info via entity_content as well as using separate form-data fields for each text value. I have also tried using the “RAW” option, but always get the multipart error message (see below)
What is the error message (if any)?
Multipart message must include a non-binary part (see below)
Here is the CURL which I am able to use succesfully
curl --location ‘https://<MY_SALESFORCE>.salesforce.com/services/data/v62.0/sobjects/ContentVersion’
–header ‘Authorization: Bearer <MY_BEARER_TOKEN>’
–header ‘Cookie: BrowserId=ran5c-8EEe-piOV_YXtb8Q; CookieConsentPolicy=0:1; LSKey-c$CookieConsentPolicy=0:1’
–form ‘entity_content=“{"Title":"CustomizedReport","PathOnClient":"IP103report.pdf", "FirstPublishLocationId": "a0Nct000000qHftEAE"}”;type=application/json’
–form 'VersionData=@“/Users//Downloads/work_order_335.pdf”
