Apollo client initiated requests since apollo client v3.9.2 in Nextjs sometimes render as undefined data about apollo-client HOT 8 CLOSED

Could you please validate if this error still persists in 3.9.3? We reverted a commit there that might have caused an issue like this.

We use renovate to update our dependencies to the latest version, so indeed we hoped that v3.9.3 would have fixed it, but the issue still remains with v3.9.3. So we reverted back to v3.8.10 which works flawlessly.

I'm seeing (I assume) the same issue on 3.9.3 but not on 3.8.10.

We have a lazy query which we fire in a useEffect, flow something like this

• First render, undefined data (no effect run yet)
• Effect runs, query fires
• Second render, we have data now
• Third render (??) now data is gone

I don't know why the third render occurs, but what is interesting to me is I see in the network log a second network call of my lazy query, but there was no second call from my useEffect - not sure what told Apollo to re-query it. The second request is also successful though FWIW.

@Slessi, @pmualaba actually that change just released on 3.9.4, not on 3.9.3 😆. Would you mind trying 3.9.4 now that its out?

@Slessi I think that might be a different issue than what is originally reported in this issue, but 3.9.4 also contained a fix for a double network call in some cases. I'd love to know if this addresses that issue.

Yea, 3.9.4 fixes both problems for me

Thanks for confirming, @Slessi. I'm going to go ahead and close this out.
