Commit
Test workflow invoking the composite action
Workflow run

Test 2: One of the error messages is encountered in the logs
Commit
Test workflow invoking the composite action
Workflow runs 1 and 2

Test 3: Single line error messages are still working
Commit
Test workflow invoking the composite action
Workflow runs 1 and 2

Test 4: Triggering the workflow through the webmodeler repo with multiple error messages retriggers the action if it fails

I don't really see why produce a map here ({"error1": "...", "error2": ...}) if it's much easier to make a flat list of strings (["...", "..."]), like this:

multiline_variable=$(cat << EOF
Process completed with exit code 88
Process completed, with exit code 99
EOF
)
result="["

for line in $multiline_variable
do
  result+="\"$line\","
done

result=$(echo $result | sed '$ s/,$//g')
result+="]"

echo $result

yeah this actually makes much more sense, will address this

Thx for all the detailed explanations and tests 🙇
I have added some comments directly in the code.
