Gitlab-CI Pipeline won't fail if a script is missing.
### Summary
I have a Gitlab-CI Pipeline which does not fail if a script is missing or not started with the correct parameters.
### Steps to reproduce
1. Set up pipeline or add a further step to an existing one.
2. Write a script with a script called inside that is missing.
### What is the current *bug* behavior?
The pipeline step does not fail but instead only writes console output that the script cannot be found and the step finishes green (if nothing else fails).
### What is the expected *correct* behavior?
The step should fail with an explaining error message.
### Relevant logs and/or screenshots
