I’m trying to send data to a variable on bucket from Analisys, but it’s not working.

I’m getting this message on Console:
{‘status’: False, ‘message’: ‘Function Parse Error: TypeError: Cannot convert undefined or null to object’}

This is part of my code:

data = {
‘variable’: ‘energy_today’,
‘value’: str(round(energy_today,2)),
}

result = my_device.insert(data)

context.log(result)

Could someone help me?
