The SNIPPET action is supposed to grab a fresh bearer token before the REST Proxy calls hit the recording API. We’re hitting /oauth/token with grant_type=client_credentials. Studio flow assigns the body string. Response keeps dropping a 401 Unauthorized. The client secret definitely isn’t the issue since the same creds work in Postman. Is there a specific header requirement we’re missing in the ASSIGN block? The token endpoint seems to reject the POST entirely when coming from the proxy.
