Error while creating a flow

[y-aoub]

I tried to create a new flow and add it to the database, like this. But, I have the error below even if the id and type are defined. Weird!

PET_LC.id = str(uuid.uuid4())
PET_LC.flow_type = olca.FlowType.PRODUCT_FLOW 
PET_LC.name = 'PET_LC'
PET_LC.description = 'PET Bottle Life Cycle'

#items = client.find(olca.FlowProperty, ‘Number of items’) 
items = olca.FlowProperty()
items.name = 'Number of items'

items_factor = olca.FlowPropertyFactor() 
items_factor.conversion_factor = 1.0
items_factor.flow_property = items 
items_factor.reference_flow_property = True
PET_LC.flow_properties = [items_factor]

client.insert(PET_LC)```

Seems like the id of the flow property is missing. Also, you need to make sure that the flow property exists in the database before you insert the flow.
