Steps to Reproduce

Steps to reproduce the behavior:

1. Import via fitbit
2. Go to Exercises and change the category from blank to eg "cardio"
3. Confirm "Sync Past Entries"

Environment

[CodeWithCJ]

Set SPARKY_FITNESS_SAVE_MOCK_DATA=true to your Server container, sycn Fitbit to generate JSON under mock_data. Share me the anonymized file to me via docker. As I don't have Fitbit, I tested only few that I was able to add manually in fitbit web portal.

It will be created in server container under /app/SparkyFitnessServer/mock_data. You can also create a volume mapping so you can access easily for this app. in your docker compose for server section edit below

volumes:      
      - ./mockup_data:/app/SparkyFitnessServer/mock_data

update v0.16.4.4 and for this fix
