I have an elixir phoneix application that receives Stripe webhooks to update payment status in the database, I have a problem, sometimes my webhook endpoint does not return a response to stripe so the webhook will be failed.
When I looked in the logs : I found that sometimes the request does not pass through the Plug (in the Plug I check the signature of the webhook), and then the request can reach the Controller function.
Maybe add an IO.inspect(stripe_event) after this or wrap the assignment like so
|> IO.inspect(label: "conn before when signature OK")
|> Plug.Conn.assign(:stripe_event, stripe_event)
|> IO.inspect(label: "conn after when signature OK")
to determine if there’s anything unexpected going on with the conn that do not reach the function in the controller.
The request could also potentially be reaching the controller and just not matching on webhooks_payment if there’s no catchall function head e.g. def webhooks_payment(conn, params), do: IO.inspect(conn, label: "conn from catchall webhooks_payments")
