React Async Select loadoption sometimes fail to loads the option. This is a very strange phenomenon after couple of set of queries react loadoptions don't load any value but i can see from log that results properly came from backend query. My codebase is totally up to date with react-select new release and using

"react-select": "^2.1.1"

Here is my front end code for react-async select component. I do use debounce in my getOptions function to reduce number of backend search query. This should not cause any problem i guess. I would like to add another point that i observe in this case, loadoptions serach indicator ( ... ) also not appear in this phenomenon.

I do not have access to the build server, I can only modify the files. So I can't add any flags to the grunt command. The build server seems to simply run "grunt". I have tried all sorts of configurations without success, suggested here and other sources.

From my understanding webpack should by default build a production build but perhaps it was introduced in later versions of webpack only or not supported by grunt-webpack?
