docker.errors.BuildError in my submission

I received the following error in my submission #146158

docker.errors.BuildError: The command ‘/bin/sh -c conda env update -p ${NB_PYTHON_PREFIX} -f “environment.yml” && conda clean --all -f -y && conda list -p ${NB_PYTHON_PREFIX}’ returned a non-zero code: 1

Any idea how to fix it? I am new to building a docker environment.
