** (EXIT from #PID<0.8019.0>) an exception was raised: ** (ArgumentError) errors were found at the given arguments

Hello and welcome,

Can You provide some code?

It’s hard to understand what You are trying to do…

yes
here is the code.

@base_url “http://administration.example.com/api/checks”

setup do
admin = AppCount.UserHelper.new_admin(%{roles: [“Admin”]})

{:ok, %{check: insert(:check), admin: admin}}

end
test “SHOW /api/checks/:id”, %{check: check, admin: admin, conn: conn} do
response =
conn
|> admin_request(admin)
|> get(@base_url <> “/#{check.id}”)
|> json_response(200)

assert is_binary(response)

end

getting error in this test case

The code you posted doesn’t seem directly related to this error, but here’s what I can gather from the stacktrace:

• something (maybe in another test?) is starting a Task that calls AppCount.Data.Utils.PDF.write_tmp_pdf/2
• that function depends on an ETS table named :fake_http_client
• that table doesn’t exist anymore. Maybe it’s deleted by code in an on_exit?

This can happen if you’re testing something that launches a Task as a side-effect but not waiting for the task to complete.
