Credential Value pill does not work with Test REST Step buttonDescriptionWhen you use the Test REST Step button, the Connection Value pill resolves to an empty string.This seems to occur regardless of auth type.Originally noticed for OAuth, but was reproduced with Basic Auth.Steps to Reproduce Enable full HTTP Logging with the following sys properties:glide.outbound_http_log.override=trueglide.outbound_http_log.override.level=ALLMake a Connection and Credential Alias with a basic auth credential.Put that C&CA into a REST step in an action.Put the Credential Value pill into the Authorization header and save it.Test the whole action, and check the headers in [sys_outbound_http_log].This will have the credential value in the header as expected.Use the Test REST Step button this time.The Authorization header will now be empty when you check [sys_outbound_http_log] when the value should be there.WorkaroundThe only workaround at the moment is to use the "Test" button instead of 'test rest step' button to avoid the 401 response This problem is currently under review.
