spotify playlist returns error

[cloudlena]

When I run spotify playlist, I get the following error:

$ spotify playlist
(node:6473) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
(node:6473) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Is it maybe because my spotifyClientID is the same as my spotifyUsername? Local commands like spotify play work fine.
