In my application I have been calling google prediction API continuously for an array(size: 4000 aprox) of strings. I observed that after some api calls it gives response as Undefined
, it continues for some api calls and then it gives response fine. But this is happening frequently.
I have checked their api documentation, but couldn't find any rate limit or any such restriction. Also there was no error logged in Google API manager dashboard.
Does anyone have any idea why its happening like that.
