Data streaming service doesn't display HTML page, stuck loading

Perhaps place a nofeaturetester where the output continues to the html writer, but the no output port is connected to a terminator

NB. you will need to manually upload the nofeaturetester to FME Flow, follow the message that pops up when publishing

Be sure to include the (HTML) “writer in stream”

Other options might be to make use of Notification Topics, 

Note: You can specify your own topics to receive success or failure notifications in the following situations: When you publish a workspace to FME Server to the Data Download or Job Submitter services. In an Automations workflow that contains a Notify an FME Server Topic external action.

  use the ‘Edit’ of the Data Streaming service when publishing. 

but you might need an additional writer 

Thank you for your reply j.botterill, although I am having a bit of trouble following your instruction.



I think if I can somehow terminate the workbench after the html output has been generated then the message may appear, as the data streamer is stuck in that constant loading state until I hit X on the browser. Possibly if the workbench is terminated it may stop that loading state?
 

Yes you might need to consider the Workspace Parameters > Rejected feature handling settings

If you set it to Continue, then the terminator transformer can be used. But perhaps in this Data Streaming to HTML writer, you may want to set it to Terminate
