I am calling an IBM cloud function (https://eu-gb.functions.cloud.ibm.com/api/v1/web/akash_IBM_dev/default/Demo) from IBM Watson assistant chatbot webhook and getting error - "Webhook call failed; response code 401 Unauthorized. Add the Authorization header under your skill options (or under workspace.webhooks.headers). (and there is 1 more error in the log)".
In the documentation it was mentioned "Cloud Functions web actions do not need to be authenticated" so I have not added headers in webhook option.
How to resolve it ?
