Salesforce to Clay Webhook Setup: Handling Response Type Issues

I'm trying to set up a Salesforce > Clay webhook for realtime inbound enrichment (using the "Create HTTP Callout" flow action in SF and a "Pull in data from a webhook" action in Clay), and while the Clay table is receiving the webhook payload I'm getting an error in Salesforce that "expected declared response media type application/json, but got text/plain; charset=utf-8." I should be able to handle a text response from Clay in SFDC, but while I'm figuring out how to do that was wondering if someone could confirm that a text response is expected from Clay or if I configured something wrong, OR if there's a way to handle this and convert to JSON on the Clay side. Thanks!
