Question: use saveItem with loadFromObservable?

[boye]

Perhaps I have overlooked something in de docs, but I am wondering if I need to use saveItem first before I call loadFromObservable? My plan is to integrate ionic-cache into my generic Api provider that handles all HTTP traffic. I have something similar to the loadList example:

request(method: string, endpoint: string, body: any, options?: RequestOptions): Observable<any> {
    // Some other code
    ...
    const apiCall = this.http.get(url, options);
    const key = `prefix:${endpoint}`;
    return this.cache.loadFromObservable(key, apiCall.map(res => res.json()));
  }

However, using it like this results in a Runtime Error saying "No such key". Therefore I thought I might be calling saveItem first? Can you perhaps point me in the right direction?

Many thanks!

Sorry for late response. No it's not needed, this looks like a bug. Did you got this exception everytime or only sometimes?

Did you installed @ionic/storage?

I worked around it by calling loadFromDelayedObservable instead of loadFromObservable . Thanks for replying though :)
