Unable to export variables from within container to slack-orb config to notify users about results from a CircleCI build

Build Environment

Hello all.
We have an issue with CircleCI version: 2.1 as we cannot export properly the variables from within the container to Circle (slack orb ) . We receive blank spot in the slack notification ; I can see from the output from build results that variable has value in container before exporting.
Idea of doing this is to get results in the slack notification message directly as we do plenty of builds daily and to see at which job the build has failed .

I’ve used as example :

  1. Echo/Evaluate external variable to slack orb
    2.Leveraging CircleCI API to include build logs in Slack notifications

Have used from Circle documentation : For alpine image

version: 2.1
jobs:
build:
shell: /bin/sh -leo pipefail
environment:
- BASH_ENV: /etc/profile

As suggested there , we also tried
echo “export SLACK_MESSAGE=‘${SLACK_MESSAGE}’” >> $BASH_ENV

We tried redirecting to :
1.>> ~/.bash_profile
2./etc/profile ( had permission issues so i had to adapt using : echo -e ‘export COMMITTER_NAME_VAR=“${COMMITTER_NAME}”’ | sudo tee -a $BASH_ENV )
3. ~/.profile ( as .bash_profile and .bash_login are missing )

Here SLACK_ERROR_MESSAGE is the custom variable while all the rest are the built-in from circleCI (https://circleci.com/docs/2.0/env-vars/#built-in-environment-variables) .
We have 2 cases: one from failed build and other from success.

Give empty value already, while export commit=“John” is displayed but not exported to slack.

I am available to provide any other information needed . Thank you in advance.
