Custom Action Authentication Hi All, I am trying to make a third party API call via custom action. I added the required authentication details and the test authentication is successful as in the below screenshot. Below is the Authentication payload used{"type": "customAuthorization","authorizationType": "Bearer","endpoint": "//url//","method": "POST","headers": {},"body": {"bodyType": "form","bodyParams": {"grant_type": "client_credentials","client_id": "//client_id//","client_secret": "//client_secret","scope": "//scope//"}},"tokenInResponse": "response","cacheDuration": {"duration": 1,"timeUnit": "hours"}} But once I add this custom action into a journey it is throwing me HTTP 500 error like belowError: HTTP 500Message: can't call url <endpoint url> . HTTP protocol violation. Authentication challenge without WWW-Authenticate Header. Also observed that once I added the custom action to the very first journey, I see the same issue but it got resolved by itself after after a couple of day
