Send a csv file from the 'create CSV' module as an attachment to the 'make a basic http request' module

Hi, looking for some tips for a beginner.

I’m trying to ultimately get to a HTTP request which follows the following format:

curl -X POST "https://integrations.expensify.com/Integration-Server/ExpensifyIntegrations" \
    -d 'requestJobDescription={
        "type": "update",
        "credentials": {
            "partnerUserID":"...",
            "partnerUserSecret":"..."
        },
        "inputSettings": {
            "type": "policy",
            "policyID": "0123456789ABCDEF"
        },
        "tags": {
            "action": "replace",
            "source":"file",
            "config": {
                    "dependency":true,
                    "glCodes":true,
                    "header":true,
                    "setRequired":true,
                    "fileType":"csv"
            }
        }
    }' \
    --data-urlencode 'file@tags.csv'

I have a simple workflow:

At the end of my HTTP post, I have replaced the line ‘–data-urlencode ‘file@tags.csv’’
with ’ --data-urlencode ‘file@{{33.text}}’ but this isn’t working (I get the response ‘“Tag file is missing”’)

Any ideas how I can push the output from from my CSV connector into the HTTP request as a file attachment?

Thank you!
