When using Cloud Foundry with api version 2.0.0, and cf-cli 6.26, the command cf logs <APPNAME> -v produces the following error:

Either upgrade the Cloud Foundry installation, or downgrade the CLI (version 6.21.1 works for me).

Cloud Foundry changed the configuration of the endpoints used for logging at some point. https://www.pivotaltracker.com/n/projects/966314/stories/135557875

Version 6.26 of cf-cli expects doppler_logging_endpoint to be set, whereas v2.0.0 of the API only sends loggregator_endpoint. Thus the Websocket Request is sent to "", which results in the response being nonsense, generating this error.
