Getting errors while following Microsoft Databricks Best-Practices for DevOps Integration

I'm currently trying to follow the Software engineering best practices for notebooks - Azure Databricks guide but I keep running into the following during step 4.5: Run the test

I'm running a 11+ cluster for this process and have confirmed multiple times that my setup matches the setup in the documentation.

I'm not sure what I'm missing as this is mostly copy/paste

Closing the loop on this in case anyone gets stuck in the same situation. You can see in the images that the transforms_test.py shows a different icon then the testdata.csv. This is because it was saved as a juypter notebook not a .py file. When the script runs it's trying to access the file but breaks because it can't use the notebook. Re-creating the file as a .py fixed the issue.
