I have gone through all of the steps in the tutorial to create a webdataconnector. I launched it with the example files and it worked once (translating all of the data into their respective places in the table at the bottom of the page). Then I tried it again and it just showed me the html code without launching it.
I've tried clearing the npm cache and relaunching but nothing else seems to get the html page to launch so that I see and can click the button to convert the data into a table in the simulator.
Has anyone had and solved this problem? Any suggestions?
