Action fails to set stdout when one of the commands has non 0 exit code

[alexvcoff]

Describe the bug

I want to get notifications with execution details (at least stdout, but having stderr would be nice as well) when script finishes, no matter what was the exit code.
Currently with capture_stdout: true set, if one of the script lines returned non 0 exit code, action fails to grab stdout and store it in action output. Also tried to redirect stderr to stdout by adding 2>&1 to the end of the failing command, but that leads to the same errors in job log:

Run echo "$GITHUB_ACTION_PATH" >> $GITHUB_PATH
