Thanks! I will add this to my If - Then - Else
@tracked rule of thump.
@jenweber Maybe this should be in the Ember Guides too.

Good call - you did remember correctly!
I clear QPs in my code (some are mutually exclusive) and this is the error I got when I removed @tracked from them. (I forgot I did track some QPs):
Error: Assertion Failed: You attempted to update <bnc@controller:application::ember224>.message to “”, but it is being tracked by a tracking context, such as a template, computed property, or observer. In order to make sure the context updates properly, you must invalidate the property when updating it. You can mark the property as
@tracked
, or use@ember/object#set
to do this.
Heads up for others reading this thread. There seems to be a performance issue when using @tracked
on queryParams properties.
See this Github issue.
I ran into this performance issue and fixed it be removing @tracked
only for the queryParam properties and then changing the queryParam properties with set()
