Describe the bug

we have a dockerized project. in the Dockerfile

COPY apps/graphql_web/mix.exs               apps/graphql_web/
COPY apps/leangoo/mix.exs                   apps/leangoo/
COPY apps/leangoo_db/mix.exs                apps/leangoo_db/
COPY apps/leangoo_file_service/mix.exs      apps/leangoo_file_service/

COPY apps/leangoo_pubsub_web/mix.exs        apps/leangoo_pubsub_web/
COPY apps/leangoo_rabbit/mix.exs            apps/leangoo_rabbit/
COPY apps/leangoo_reminder/mix.exs          apps/leangoo_reminder/
COPY apps/leangoo_reminder_web/mix.exs      apps/leangoo_reminder_web/
COPY apps/leangoo_web/mix.exs               apps/leangoo_web/
COPY apps/logger_file_backend/mix.exs       apps/logger_file_backend/
COPY apps/oauth_gateway/mix.exs             apps/oauth_gateway/
COPY apps/oauth_gateway_web/mix.exs         apps/oauth_gateway_web/
COPY config config

RUN no_proxy=192.168.0.100 mix deps.get \
    && mix deps.compile \
    && mix esbuild.install --if-missing

when docker build, it always failed with on mix deps.compile

==> appsignal
Downloading agent release
could not compile dependency :appsignal, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile appsignal --force", update it with "mix deps.update appsignal" or clean it with "mix deps.clean appsignal"

But if I comment out the mix task

COPY apps/graphql_web/mix.exs               apps/graphql_web/
COPY apps/leangoo/mix.exs                   apps/leangoo/
COPY apps/leangoo_db/mix.exs                apps/leangoo_db/

COPY apps/leangoo_file_service_web/mix.exs  apps/leangoo_file_service_web/
COPY apps/leangoo_pubsub_web/mix.exs        apps/leangoo_pubsub_web/
COPY apps/leangoo_rabbit/mix.exs            apps/leangoo_rabbit/
COPY apps/leangoo_reminder/mix.exs          apps/leangoo_reminder/
COPY apps/leangoo_reminder_web/mix.exs      apps/leangoo_reminder_web/
COPY apps/leangoo_web/mix.exs               apps/leangoo_web/
COPY apps/logger_file_backend/mix.exs       apps/logger_file_backend/
COPY apps/oauth_gateway/mix.exs             apps/oauth_gateway/
COPY apps/oauth_gateway_web/mix.exs         apps/oauth_gateway_web/
COPY config config

# RUN no_proxy=192.168.0.100 mix deps.get \
#    && mix deps.compile \
#    && mix esbuild.install --if-missing

after build the image. enter it by manual

docker run --rm -it  <the_docker_image> /bin/bash

run the mix task by manual, it compiles always successfully

no_proxy=192.168.0.100 mix deps.get \
    && mix deps.compile \
    && mix esbuild.install --if-missing

I will fork and replace :hackney with :req to see can fix it.

To Reproduce

Steps to reproduce the behavior:

• Using AppSignal for Elixir package version 2.12.0
