How to reproduce:

Use demo.py
[6] ⚖️ Body composition & weight
[4] Add weight (interactive)

Enter weight (30-300, default: 85.1): 90
Enter unit (kg/lbs, default: kg):
⚖️ Add weigh-in: 90.0 kg
❌ Error adding weigh-in result: Expected value: Row 1 Column 1 (character 0)

The cause is that a JSON response is expected in the def add_weigh_in function.
return self.garth.post(“connectapi”, url, json=payload).json()
However, the API call does not return any content.
status_code is 204 (“204 No Content”)

However, the weight is added successfully.
