Hello,
I have a workflow that builds docker image and next action is creating comment on each workflow run.
However, I need to check if build step has failed or nott and take action.

Please note, in my build.sh script, i already set set -e to prevent the execution of bash script if i get any errors.

The following workflow doesn’t work for some reason, I think i am unable to read exit_code. Any help would be much appreciated.
Thanks.

          echo "Exited with $?"
