Issue with uploading files with RCURL - r

Question

Here, I want to attach a file to certain Policy/Claim Number with the below command in the intranet URL.
library(RCurl)
options(RCurlOptions = list(
cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl"),
followlocation = TRUE,
httpheader = c(
Accept = "text/xml",
Accept = "multipart/*",'Content-Type' = "text/xml; charset=utf-8",
SOAPAction = "INTRANET URL"
),
userpwd = "USERID:PASSWORD",
netrc = TRUE,
timeout = 100,
postfields = CONTAINS SOAP DATA,
writefunction = reader$update,
verbose = TRUE,
httpauth = AUTH_BASIC)
)
getForm(
uri = "INTRANET URL",
file = fileUpload(
filename = "C:\\Users\\Username\\Desktop\\image001.pdf",
contentType = "application/pdf"
),
upload = TRUE
)
When I run the above commands, I am getting the status as "HTTP/1.1 200 OK" but the response from the service says no attachment.
