What does status=canceled for a resource mean in Chrome Developer Tools?

Question

What would cause a page to be canceled? I have a screenshot of the Chrome Developer Tools.

Answer 1

For anyone coming from LoopbackJS and attempting to use the custom stream method like provided in their chart example. I was getting this error using a PersistedModel, switching to a basic Model fixed my issue of the eventsource status cancelling out.

Again, this is specifically for the loopback api. And since this is a top answer and top on google i figured i'de throw this in the mix of answers.
