I noticed your databricks.yml uses include: - resources/*.yml, so you need to define the source_code_path in a separate file inside the resources/ folder.

Create resources/app.yml:

resources:
  apps:
    my_app:
      name: "my-streamlit-app"
      source_code_path: ./app  # Path to your app files relative to databricks.yml

Then, adjust the path based on your structure. The path should point to where your app.py and requirements.txt live. Let me know if that does the trick.
