Ash.page resulting in ** (EXIT) no process: the process is not alive or there's no process currently

My paginated read query is failing with this error. This used to work fine, so I wonder if something changed with Ash.

This is either fixed in main or in the latest release I believe Please try and let me know

jasonoOP•4mo ago

Hmm.. tried both, but the issue persists.

ZachDaniel•4mo ago

Can you make a reproduction project showing the issue?

Jason•4mo ago

Okay. I will try.

@Zach Daniel It appears that the error occurs when loading multiple relationships in each pagination request.

  Ash.Query.for_read(Ticket, :paginated)
      |> Ash.Query.limit(page_size)
      |> Ash.Query.sort(priority: :desc, created_at: :desc)
      |> Ash.Query.load([:events, :comments]). ## multiple relationship

  Ash.Query.for_read(Ticket, :paginated)
      |> Ash.Query.limit(page_size)
      |> Ash.Query.sort(priority: :desc, created_at: :desc)
      |> Ash.Query.load([:events, :comments]). ## multiple relationship

Let me know if this makes sense. If not, I will provide a link to the test project. Thanks.

Hmm...strange. A link to the project would be great. Just makes it that much easier for me 🙂

jasonoOP•4mo ago

Sure.

mix run run_pagination_test.exs reproduces the error.
