unaccessible item unit

Question

Dear all,

again it´s me. still at the hunt for units...

In my model I need masses, energies and items.

mass_flow_property=client.get(schema.FlowProperty, name="Mass") # unit Mass

energy_flow_property=client.get(schema.FlowProperty,name="Energy") # unit energy

item_flow_property=client.get(schema.FlowProperty,name="Items") # unit items

print(mass_flow_property)

print(item_flow_property)

This code leads to the following error messages:

WARNING:root:failed to get entity of type <class 'olca_schema.schema.FlowProperty'>: 404: resource not found

FlowProperty(id='93a60a56-a3c8-11da-a746-0800200b9a66', category='Technical flow properties', description=None, flow_property_type=<FlowPropertyType.PHYSICAL_QUANTITY: 'PHYSICAL_QUANTITY'>, last_change='2024-11-29T10:39:13.667072Z', name='Mass', tags=None, unit_group=Ref(id='93a60a57-a4c8-11da-a746-0800200c9a66', category='Technical unit groups', description=None, flow_type=None, location=None, name='Units of mass', process_type=None, ref_unit=None, ref_type=<RefType.UnitGroup: 'UnitGroup'>), version='00.00.000')

None

Due to the printout it seems that the first error message belongs to the Item_flow_property, which cannot be generated since the Item group was not found (I tried this with the UUID too..). Can anybody help me on that? My combination is OpenLCA 2.3 and ecoinvent 3.9.

Kind regards, Dieter

Hi Dieter,

Could you double-check that the flow property is named Items? The default name from openLCA reference data would be Number of items.

Also, when using the UUID, make sure to remove name=. For example:

item_flow_property = client.get(schema.FlowProperty, "01846770-4cfe-4a25-8ad9-919d8d378345")

Regards,

François

Thanks, "Number of items" worked but not the UUID (I tried it in the right way before) :) moving now to the next mineflied... :)
