PRODUCES: Could not resolve breakpoint
+ERROR: TypeError: this._dispatcher is not an Object. (evaluating 'eventName in this._dispatcher')
I have discovered what can cause this. I've made sure tests register a ScriptProfilerObserver and I've made the error message clear about which domain is missing having a dispatcher registered:
ERROR: No domain dispatcher registered for domain 'ScriptProfiler'
So this shouldn't happen anymore, and if it does we have a clear path to a solution. Closing this.
