I am trying to cross-compile an Elixir release within a Docker container for amd64 on a M1 Macbook and I receive the following error when calling mix deps.compile:

The Docker image I am building from is elixir:latest with the --platform=amd64 flag set.

#0 3.446 Error while loading project :decimal at /app/deps/decimal

Any suggestions on how to solve this? It builds fine when trying on the same arm64 Docker image so I assume I am missing something.
