I have not yet seen this during my phoenix baby steps, are you using a 1.4 preview?

The fallback controller looks like this:
defmodule MyApiWeb.FallbackController do
@moduledoc """
Translates controller action results into valid `Plug.Conn` responses.
See `Phoenix.Controller.action_fallback/1` for more details.
"""
use MyApiWeb, :controller
def call(conn, {:error, %Ecto.Changeset{} = changeset}) do
conn
|> put_status(:unprocessable_entity)
|> render(MyApiWeb.ChangesetView, "error.json", changeset: changeset)
end
def call(conn, {:error, :not_found}) do
conn
|> put_status(:not_found)
|> render(MyApiWeb.ErrorView, :"404")
end
end
tried this {:ok, user} and i removed the fallback controller and then it gave a new error :
(exit) an exception was raised:
** (Protocol.UndefinedError) protocol String.Chars not implemented for %Stripe.Customer{account_balance: 0, business_vat_id: nil, created: 1532261740, currency: nil, default_source: nil, delinquent: false, description: "Monthly subscription", discount: nil, email: "fs@as.com", id: "cus_DHExEBEuX9Jks8", invoice_prefix: "3AB85AC", livemode: false, metadata: %{}, object: "customer", shipping: nil, sources: %Stripe.List{data: [], has_more: false, object: "list", total_count: 0, url: "/v1/customers/cus_DHExEBEuX9Jks8/sources"}, subscriptions: %Stripe.List{data: [], has_more: false, object: "list", total_count: 0, url: "/v1/customers/cus_DHExEBEuX9Jks8/subscriptions"}}
as for using the preview, i just installed phoneix a few days ago so I am not aware of using preview version.
Also I tried what khm idiot suggested and with that for the first try it went throug nicely but for the second one got the stripe user printed out and got the same fallback error

The original error says that no function head in MyApiWeb.FallbackController matches what’s returned from your create controller action. MyApiWeb.FallbackController, judging by your code snippet, can match either {:error, %Ecto.Changeset{} = changeset} or {:error, :not_found}, and nothing else. So if it receives, for example, %Stripe.User{}, it just doesn’t know what to do with it. You can add a new function which would match what’s returned from the create action and the error would disappear, but I doubt that’s what you actually want. I think the real problem is with the pattern in your with statement, {:ok, %t{} = t}.

But printed out where? If you mean IO.inspect, then for which label, unmatched? If so, then that’s your solution right there – fix your pattern in with to match on a stripe user so that it doesn’t fail.
