Potential issues, bugs, or flaws:

1. /Dockerfile
   • The Dockerfile change to use a specific image digest with FROM python:3.7-buster@sha256:65f08bc4dfb68700010a2ea85fd385de826f624ede6349b05a65aa857456f987 is generally a good practice for reproducibility and stability. However, it's important to be aware that using a digest will prevent the image from being automatically updated when a new version is released. Ensure that the trade-off between stability and regular updates is acceptable for the project's requirements.

Suggestions, improvements, etc.:

1. /Dockerfile
   • Ensure that the usage of a specific image digest is a deliberate decision, understanding the implications of potential inflexibility in future updates.
