Backendless is not defined

Hi guys,
I’m just reviewing some of my created APIs, and I see some new warnings that were not there before.

One is Backendless is not defined.

The other is related to async functions.

Does this affect the functionality of existing and new APIs that I create? Why does it show up now? Thanks.

hello @Junwei_Fang

looks like you have not import backendless in some of your files

I’m using the codeless blocks only, and this messages never showed up before. Is there some change on the server side? and How do I import and which files? Thx
