useLazyQuery load function refetches from network regardless cache and variables

[anfinil]

According last refactoring:

apollo-client/src/react/hooks/useLazyQuery.ts

Line 48 in bc6488c

result && result.refetch(executeOptions?.variables);

apollo-client/src/core/ObservableQuery.ts

Line 334 in 6a5ae8a

reobserveOptions.fetchPolicy = 'network-only';

useLazyQuery load function will refetch data from network every time even with the same variables and regardless cache and fetchPolicy.

Desired behaviour: if load function results are cached (variables are the same), it shouldn't request network.

Having the same problem over here, was going crazy trying to find out why my cached responses did still requests to the server.

same here

I noticed the same issue when I was analyzing network requests with Chrome inspector

Same problem here, I fixed it by returning to v3.4.17, I don't know why this feature changed in recent versions :/, maybe someone knows something about it

Seeing this behavior as well, additionally for my case of trying to fetchPolicy: 'cache-only' the fetch-policy is only respected on the first call. On subsequent calls a request is made to the network every time.

const [
    getLargeWarehouseSetCached,
    { loading: loadingLargeSetCached, error: errorLargeSetCached, data: dataLargeSetCached },
  ] = useLazyQuery(GET_WAREHOUSE_FULL, {
    fetchPolicy: 'cache-only',
  });

First Call: Only returns from cache - however, if there is no cached information there is no error as the documentation describes.

Second & additional calls: Always make a network request.

Reverting to 3.4.17 also fixed it for me, thanks @LiamKlyneker

@anfinil @Ccastillo06 @orelHAnyvision @mcsimps2 @LiamKlyneker @CowDotDev @sarink Can you try the latest v3.6 beta by running npm i @apollo/client@beta when you have a chance (currently 3.6.0-beta.11)? I believe PR #9564 will help here (assuming this issue is similar to #9375). Thanks for your patience!

@benjamn Can confirm I'm no longer seeing cache-first queries refetched with 3.6.0-beta.11. Thank you for the fix! 🎉

[anfinil]

@benjamn I can confirm that fix is working.
