investigate issue reading trajectories from deployed app

[simonpcouch]

read_trajectories("<tiles-agent-url>")
#> Error in `resp_body_raw()`:
#> ! Can't retrieve empty body.

Same with just providing the GUID.

With

    if (!httr2::resp_has_body(resp)) {
      break
    }

I just get an empty list.

Connect shipped a change to the internal env yesterday that changes the shape of the traces API and the way that apps should interact with it. Old traces will no longer be accessible
