J.ok and also check if the content-type includes application/json. You'd be surprised at how many APIs are wonky sometimes and return a 200 but an HTML error page or somethingJ
.properties doesn't exist there, you'll get a TypeError. I'd check proto_res.properties exists too

Aperformance.now() isn’t available in Workers and Date.now() doesn’t increment unless you do I/O is there any way to actually benchmark CPU bound function execution times in a worker?KKperformance.now() is available but it just calls Date.now()AAinternal server error anyplace to look to see better logging?A
WWAAWWWapp.onError to add your own handlerAAAAA
CJA
also this explains lots too. just ignore the dashboard one J yeah, you're best just to ignore the production
