The issue depends on the request parameters being passed in the request body rather than as query parameters.

There was a problem hiding this comment.
This should not be set to datafeedId and is overwritten in TransportStopDatafeedAction

If a stop datafeed request is sent to a non-master node and the request contains parameters in the request body e.g.
then a NullPointerException is thrown streaming the request as one of the fields is not initialised by all constructors.
Before this fix an alternative is to pass the options as query parameters in which case the field is safely initialised.
