feat: application logs

[DevQuandt]

Is your feature request related to a problem? Please describe. My Problem is when I try to create a new json for my uploader it seems to be no longer working. I migrated the json like mentioned in the Readme.MD. I can try a sample upload but the error does not help with trouble shooting "An error occurred during the upload process."

Describe the solution you'd like Have application logs to see what request the application does and what response it receives.

You should be able to see logs via Console but I do agree a log file in the application directory is a good idea
