During the initial handshake where a token and username are passed, I am catching this strange error--

    { handle: 10,

      type: 'error',

      className: 'Error',

      constructorFunction: { ref: 11 },

      protoObject: { ref: 12 },

      prototypeObject: { ref: 3 },

      properties: 

      [ { name: 'stack',

          attributes: 2,

          propertyType: 3,

          ref: 3 },

        { name: 'arguments',

          attributes: 2,

          propertyType: 1,

          ref: 3 },

        { name: 'type',

          attributes: 2,

          propertyType: 1,

          ref: 3 },

        { name: 'message',

          attributes: 2,

          propertyType: 1,

          ref: 13 } ],

        text: 'Error: Not enough or too many segments' }

malformed JWT? initial token malformed?

If you are using JWT-simple, by looking at the source code, we can see that this error is caused by the token having an incorrect form.

//...



var segments = token.split('.');

if (segments.length !== 3) {

  throw new Error('Not enough or too many segments');

}
