I am using Ecto Tds to connect to MS SQL server and till today everything worked fine. I am developing on OS X and deploying application on EC2 instance with Ubuntu 20.04. I build release in Docker with following Dockerfile

FROM ubuntu:20.04 as production-environment
ENV LANG=en_US.UTF-8
ENV DEBIAN_FRONTEND noninteractive

RUN \
  apt-get update -y && \
  apt-get install -y git curl wget locales gnupg2 build-essential && \
  locale-gen en_US.UTF-8 && \
  wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb && \
  dpkg -i erlang-solutions_2.0_all.deb && \
  rm erlang-solutions_2.0_all.deb && \
  apt-get update -y && \
  apt-get install -y esl-erlang elixir

CMD ["/bin/bash"]

Today suddenly after deploying new version application stopped working with following error:

After short investigation I found out that build in Docker used OTP 25 while on my local machine I was still using OTP 24 and installing Elixir 1.13.4-otp-25 resulted in the same error.

I was not able to find any issue related to this reported on Tds so I wonder if anyone have noticed similar problem or has an idea what could cause this error?
