Error: WebDAV authentication failed. Please (re-)authenticate first by running ´sfcc-ci auth:login´ or ´sfcc-ci client:auth´. No token auto-renewal is performed. If the problem still occurs please check the WebDAV Client Permissions on the instance and ensure your client ID has been granted access to required WebDAV resources.
