no such key

[watermelon-brother]

hi! I use the function which is the loadFromObservable in ionic3.it cause a error when run. error: Uncaught (in promise): No such key: http://ip.jsontest.com

my function(it's your demo,why?) loadList() { let url = "http://ip.jsontest.com"; let cacheKey = url; let request = this.http.get(url).map(res => res.json());

return this.cache.loadFromObservable(cacheKey, request);

}

I get this when there's nothing on the cache, I have a calendar page and when I load it, inside my ionViewDidLoad I call my api service which retrieves all the events that's when I get the 'no such key'

you can use like this this.cache.loadFromObservable(cacheKey, request).subscribe(); @Alberick0

Same problem here. If the cache-item is empty, there is the message, that there is no key.

Have to use like this below to overcome this issue,

loadList() { let url = "http://ip.jsontest.com"; let request = this.http.get(url);

return this.cache.loadFromObservable(url, request).subscribe((res:Response) => {res.json()});

try to replace subscript with subscribe
