Encounter - pagination issues

[Mikhail Polatov]

Hi,

Seeing this pretty often, not sure if that's Sandbox artifact, or a standard behavior.

Get code 500 back with {"resourceType":"OperationOutcome","issue":[{"severity":"fatal","code":"exception","details":{"text":"Internal service error from resource store"}}]}

Please advise.

Thank you,

interested in this issue too.  we've had those for various resources, not rare.  using the returned link we usually get a 404, vs a 500.  i think the 500's are confined to sandbox, don't recall for sure.

i always surmised a fhir code fault at end-of-data, ie the end of the previous page was the end of the result set, or possibly a single result should have been included in the failed NEXT.

Hello,

Thanks for reporting this. We are currently taking a look into it!

Thanks,

Fenil

Thanks,

My apologies - small correction - the first response *may not be empty*, but still, a link to next resultset exists, and results in 500/Internal service error from resource store.

Thanks,

-Mikhail

We have found a bug on our side related to this, currently impacting our Sandbox. We will be working to fix this soon.

[Mikhail Polatov]

Fantastic, thank you!

So there would be no link if a resultset concludes the end right?

Would save everybody a round-trip and you precious processing cycles.
