Describe the bug

A clear and concise description of what the bug is. Plain-text snippets preferred but screenshots welcome.
The App Gen DAG should fail if there is an error in the entrypoint.sh i.e. cannot clone the provided git repo
Right now, it is not failing, it still shows up as successful but no credentials are printed in the logs
If I change the entrypoint.sh that creates the application package to return exit code 1 when there is an error, then the credentials are printed in the logs

I think there are 2 ways to approach this and I already tried the first option:

1. More securely pass the credentials so that they are not printed when the DAG is printed on error. I tried passing as arguments, env vars, using the env parameter, using the from_env parameter, started looking into using kubernetes secrets
2. Change something so that the failed DAG is not printed on fail
   I will also need to make modifications to the entrypoint.sh so that it exists with exit code nonzero when there is an error

Reproducible steps

How would we reproduce this bug? Please walk us through it step by step. Plain-text snippets preferred but screenshots welcome.

1. Register the App Gen DAG from unity-sps/airflow/dags/appgen_dag.py
2. Trigger the DAG with a nonexistent repo
3. The DAG will say it is successful but the logs say that it failed to execute all of the entrypoint.sh
