Saya mencoba memasukkan catatan ke dalam database secara asinkron menggunakan Elixir.Task di pengontrol Phoenix. Pengujian yang mencakup metode pengontrol tersebut, mencatat pengecualian bahwa kesalahan koneksi DB (DBConnection.OwnershipError).
Saya mencoba mengatur pengujian pengontrol sebagai async sehingga mode Ecto.Adapters.SQL.Sandbox akan dibagikan.

Catatan:
05:28:21.325 [error] Task #PID<0.438.0> started from #PID<0.436.0> terminating
** (DBConnection.OwnershipError) cannot find ownership process for #PID<0.438.0>.
When using ownership, you must manage connections in one
of the four ways:
* By explicitly checking out a connection
* By explicitly allowing a spawned process
* By running the pool in shared mode
* By using :caller option with allowed process
The first two options require every new process to explicitly
check a connection out or be allowed by calling checkout or
allow respectively.
The third option requires a {:shared, pid} mode to be set.
If using shared mode in tests, make sure your tests are not
async.
The fourth option requires [caller: pid] to be used when
checking out a connection from the pool. The caller process
should already be allowed on a connection.
If you are reading this error, it means you have not done one
of the steps above or that the owner process has crashed.
See Ecto.Adapters.SQL.Sandbox docs for more information.
