Reference layer's labels crashes app on locally deployed app

[Fish4Food]

Downloaded and deployed app to web server, everything worked as expected with referenced webmap (just one webmap being used, two layers). Added a third layer as a reference layer, and enabled labels in the webmap for that layer, and the app crashes. Disabled labels on the reference layer, app runs as expected.

Hi Ryan,
Anyway you can share the web map that causes the crash? I can try to have a look if so.

Thanks,
Mark
