Duplicate errors between Sentry.LoggerBackend and Sentry.Plug

[hfjallemark]

Environment

• Elixir version (elixir -v): 1.9.1
• Erlang/OTP version (erl): 22
• Sentry version (mix deps): 7.2.0
• Operating system: macOS Catalina

Description

When adding the Sentry.LoggerBackend I am receiving duplicate events for request errors. Inspecting the logger backend code:

sentry-elixir/lib/sentry/logger_backend.ex

Line 93 in c27a529

match?({^module, ^function, ^arity}, {Phoenix.Endpoint.Cowboy2Handler, :init, 2})

it seems it is looking for {Phoenix.Endpoint.Cowboy2Handler, :init, 2} but when my error occurs the stack trace contains {Phoenix.Endpoint.Cowboy2Handler, :init, 4} (arity 4 instead of 2).

Expected Behavior

Sentry should only log the Plug error that contains all the request meta data.

Actual Behavior

Sentry reports two errors, one with the request meta data and one without.

Steps to Reproduce

Configure both the Sentry plug and LoggerBackend and then throw an error in a controller action.
